Due to the internal propagation delay of typical 100 ns, the actual current exceedsthedccurrentlimitthresholdbyasmallamount.Thetypicalpeakcurrentlimitcanbecalculated: V I = I + IN × 100ns peak(typ) LIM L V I = 400mA + IN × 100ns for theTPS61040-Q1 peak(typ) L V I = 250mA + IN × 100ns for theTPS61041-Q1 peak(typ) L (1) Thehighertheinputvoltageandthelowertheinductorvalue,thegreaterthepeak. By selecting the TPS6104x, it is possible to tailor the design to the specific application current limit requirements. A lower current limit supports applications requiring lower output power and allows the use of an inductor with a lower current rating and a smaller form factor. A lower current limit usually has a lower output voltage ripple as well. Copyright©2002–2016,TexasInstrumentsIncorporated SubmitDocumentationFeedback 9 ProductFolderLinks:TPS61040 TPS61041

TPS61040,TPS61041 SLVS413I–OCTOBER2002–REVISEDDECEMBER2016 www.ti.com Feature Description (continued) 7.3.2 SoftStart All inductive step-up converters exhibit high inrush current during start-up if no special precaution is made. This can cause voltage drops at the input rail during start up and may result in an unwanted or early system shut down. I LIM 4 The TPS6104x limits this inrush current by increasing the current limit in two steps starting from for 256 I LIM 2 cyclesto forthenext256cycles,andthenfullcurrentlimit(seeFigure15). 7.3.3 Enable Pulling the enable (EN) to ground shuts down the device reducing the shutdown current to 1 μA (typical). Because there is a conductive path from the input to the output through the inductor and Schottky diode, the output voltage is equal to the input voltage during shutdown. The enable pin needs to be terminated and should not be left floating. Using a small external transistor disconnects the input from the output during shutdown as showninFigure17. 7.3.4 UndervoltageLockout An undervoltage lockout prevents misoperation of the device at input voltages below typical 1.5 V. When the inputvoltageisbelowtheundervoltagethreshold,themainswitchisturnedoff. 7.3.5 ThermalShutdown An internal thermal shutdown is implemented and turns off the internal MOSFETs when the typical junction temperature of 168°C is exceeded. The thermal shutdown has a hysteresis of typically 25°C. This data is based onstatisticalmeansandisnottestedduringtheregularmassproductionoftheIC. 7.4 Device Functional Modes 7.4.1 Operation The TPS6104x operates with an input voltage range of 1.8 V to 6 V and can generate output voltages up to 28 V. The device operates in a pulse-frequency-modulation (PFM) scheme with constant peak current control. This control scheme maintains high efficiency over the entire load current range, and with a switching frequency up to 1MHz,thedeviceenablestheuseofverysmallexternalcomponents. Theconvertermonitorstheoutputvoltage,andassoonasthefeedbackvoltagefallsbelowthereferencevoltage of typically 1.233 V, the internal switch turns on and the current ramps up. The switch turns off as soon as the inductor current reaches the internally set peak current of typically 400 mA (TPS61040) or 250 mA (TPS61041). See Peak Current Control for more information. The second criteria that turns off the switch is the maximum on- time of 6 μs (typical). This is just to limit the maximum on-time of the converter to cover for extreme conditions. As the switch is turned off the external Schottky diode is forward biased delivering the current to the output. The switch remains off for a minimum of 400 ns (typical), or until the feedback voltage drops below the reference voltage again. Using this PFM peak current control scheme the converter operates in discontinuous conduction mode (DCM) where the switching frequency depends on the output current, which results in very high efficiency over the entire load current range. This regulation scheme is inherently stable, allowing a wider selection range fortheinductorandoutputcapacitor. 10 SubmitDocumentationFeedback Copyright©2002–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS61040 TPS61041

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The TPS6104x is designed for output voltages up to 28 V with an input voltage range of 1.8 V to 6 V and a switch peak current limit of 400 mA (250 mA for the TPS61041). The device operates in a pulse-frequency- modulation (PFM) scheme with constant peak current control. This control scheme maintains high efficiency over the entire load current range, and with a switching frequency up to 1 MHz, the device enables the use of very small external components.

The selection of the inductor together with the nominal load current, input and output voltage of the application determines the switching frequency of the converter. Depending on the application, inductor values from 2.2μH to 47 μH are recommended. The maximum inductor value is determined by the maximum on time of the switch, typically 6 μs. The peak current limit of 400 mA/250 mA (typically) should be reached within this6-μsperiodforproperoperation.

TPS61040,TPS61041 SLVS413I–OCTOBER2002–REVISEDDECEMBER2016 www.ti.com The inductor value determines the maximum switching frequency of the converter. Therefore, select the inductor value that ensures the maximum switching frequency at the converter maximum load current is not exceeded. Themaximumswitchingfrequencyiscalculatedbythefollowingformula: V ´(V -V ) f = IN(min) OUT IN S(max) I ´L´V P OUT where • I =PeakcurrentasdescribedinPeakCurrentControl P • L=Selectedinductorvalue • V =Thehighestswitchingfrequencyoccursattheminimuminputvoltage (2) IN(min) If the selected inductor value does not exceed the maximum switching frequency of the converter, the next step istocalculatetheswitchingfrequencyatthenominalloadcurrentusingthefollowingformula: 2´I ´(V -V +V ) f (I )= load OUT IN d S load I 2´L P where • I =PeakcurrentasdescribedinPeakCurrentControl P • L=Selectedinductorvalue • I =Nominalloadcurrent load • Vd=Rectifierdiodeforwardvoltage(typically0.3V) (3) Asmallerinductorvaluegivesahigherconverterswitchingfrequency,butlowerstheefficiency. The inductor value has less effect on the maximum available load current and is only of secondary order. The best way to calculate the maximum available load current under certain operating conditions is to estimate the expected converter efficiency at the maximum load current. This number can be taken out of the efficiency graphsshowninFigure1throughFigure4.Themaximumloadcurrentcanthenbeestimatedasfollows: I 2 ´L ´ f P S(max) I = h load(max) 2´(V - V ) OUT IN where • I =PeakcurrentasdescribedinPeakCurrentControl P • L=Selectedinductorvalue • fS =Maximumswitchingfrequencyascalculatedpreviously max • η=Expectedconverterefficiency.Typically70%to85% (4) The maximum load current of the converter is the current at the operation point where the converter starts to enter the continuous conduction mode. Usually the converter should always operate in discontinuous conduction mode. Last, the selected inductor should have a saturation current that meets the maximum peak current of the converter(ascalculatedinPeakCurrentControl).UsethemaximumvalueforI forthiscalculation.

Smaller values might be used to reduce the noise sensitivity of thefeedbackpin. A feedforward capacitor across the upper feedback resistor R1 is required to provide sufficient overdrive for the errorcomparator.Withoutafeedforwardcapacitor,oronewhosevalueistoosmall,theTPS6104xshows double pulses or a pulse burst instead of single pulses at the switch node (SW), causing higher output voltage ripple. If thishigheroutputvoltagerippleisacceptable,thefeedforwardcapacitorcanbeleftout. The lower the switching frequency of the converter, the larger the feedforward capacitor value required.

Therefore, when concern for line regulation is paramount, the selected feedforward capacitor should be as small as possible. See the following sectionformoreinformationaboutlineandloadregulation. 8.2.2.3 LineandLoadRegulation The line regulation of the TPS6104x depends on the voltage ripple on the feedback pin. Usually a 50 mV peak- to-peakvoltagerippleonthefeedbackpinFBgivesgoodresults. Some applications require a very tight line regulation and can only allow a small change in output voltage over a certain input voltage range. If no feedforward capacitor C is used across the upper resistor of the voltage FF feedback divider, the device has the best line regulation. Without the feedforward capacitor the output voltage ripple is higher because the TPS6104x shows output voltage bursts instead of single pulses on the switch pin (SW), increasing the output voltage ripple. Increasing the output capacitor value reduces the output voltage ripple. If a larger output capacitor value is not an option, a feedforward capacitor C can be used as described in the FF previous section. The use of a feedforward capacitor increases the amount of voltage ripple present on the feedback pin (FB). The greater the voltage ripple on the feedback pin (≥50 mV), the worse the line regulation. Therearetwowaystoimprovethelineregulationfurther: 1. Use a smaller inductor value to increase the switching frequency which will lower the output voltage ripple, aswellasthevoltagerippleonthefeedbackpin. 2. Add a small capacitor from the feedback pin (FB) to ground to reduce the voltage ripple on the feedback pin down to 50 mV again. As a starting point, the same capacitor value as selected for the feedforward capacitor C canbeused. FF 8.2.2.4 OutputCapacitorSelection For best output voltage filtering, a low ESR output capacitor is recommended. Ceramic capacitors have a low ESRvaluebuttantalumcapacitorscanbeusedaswell,dependingontheapplication. Assuming the converter does not show double pulses or pulse bursts on the switch node (SW), the output voltageripplecanbecalculatedas: Copyright©2002–2016,TexasInstrumentsIncorporated SubmitDocumentationFeedback 13 ProductFolderLinks:TPS61040 TPS61041

TPS61040,TPS61041 www.ti.com SLVS413I–OCTOBER2002–REVISEDDECEMBER2016 9 Power Supply Recommendations The device is designed to operate from an input voltage supply range between 1.8 V and 6 V. The output current of the input power supply must be rated according to the supply voltage, output voltage and output current of TPS6104x. 10 Layout 10.1 Layout Guidelines Typical for all switching power supplies, the layout is an important step in the design; especially at high peak currents and switching frequencies. If the layout is not carefully done, the regulator might show noise problems anddutycyclejitter. The input capacitor should be placed as close as possible to the input pin for good input voltage filtering. The inductor and diode should be placed as close as possible to the switch pin to minimize the noise coupling into other circuits. Because the feedback pin and network is a high-impedance circuit, the feedback network should be routed away from the inductor. The feedback pin and feedback network should be shielded with a ground planeortracetominimizenoisecouplingintothiscircuit. Wide traces should be used for connections in bold as shown in Figure 23.
