TPS60140,TPS60141 www.ti.com SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 5 Description (continued) The logic shutdown function disables the converter, reduces the supply current to a maximum of 1 µA and disconnects the output from the input. Special current-control circuitry prevents excessive current from being drawn from the battery during start-up. This DC/DC converter requires no inductors, therefore, EMI is of little concern. The TPS6014x operates over a free-air temperature range of –40°C to 85°C. It is available in the small, thermallyenhanced20-pinHTSSOPpackage(PWP).

TPS60140,TPS60141 www.ti.com SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 9 Detailed Description 9.1 Overview The TPS6014x devices regulate the output voltage using an improved pulse-skip topology. In pulse-skip mode the error amplifier disables switching of the power stages when it detects an output voltage higher than 5 V. The oscillator halts and the controller skips switching cycles. The error amplifier reactivates the oscillator and starts switching of the power stages again when the output voltage drops below 5 V. The output resistance of the chargepumpiscontrolledtoimprovetherippleperformance.Thislimitstheoutputcurrenttotheminimumthatis necessary to sustain a regulated output voltage. The benefit is that the ripple performance is nearly as good as withalinear-regulationtopology. At light loads a conventional pulse-skip regulation mode is used, but the charge pump output resistance is held at a high level. The pulse-skip regulation minimizes the operating current because the charge pump does not switch continuously and hence the gate-charge losses of the MOSFETs are reduced. Additionally, all functions except voltage reference, error amplifier, and low-battery or power-good comparator are deactivated when the output is higher than 5 V. When switching is disabled by the error amplifier, the load is also isolated from the input.Thisimprovedpulse-skipcontroltopologyisalsoreferredtoas active-cyclecontrol. 9.2 Functional Block Diagrams TPS60140 IN Oscillator C1+ C1 C1− PGND _ ChargePump IN Power Stage C2+ Control + ENABLE Circuit + C2 VREF − C2− OUT PGND FB LBO _ _ Shutdown/ LBI Start-up Control + + + + − 0.8× VI − VREF GND Figure3.

TPS60140,TPS60141 SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 www.ti.com 9.4 Device Functional Modes 9.4.1 Start-UpProcedureandShutdown During start-up (that is, when ENABLE is set from logic low to logic high), the output capacitor is charged up with a limited current until the output voltage (V ) reaches 0.8 × V. When the start-up comparator detects this voltage O I limit, the IC begins switching. This precharging of the output capacitor ensures a short start-up time. In addition, the inrush current into an empty output capacitor is limited because the current through the switches is limited beforethechargepumpstartsswitching. Driving ENABLE low places the device in shutdown mode. This disables all switches, the oscillator, and control logic. The device typically draws 0.05 µA of supply current in this mode. Leakage current drawn from the output isaslowas1µA(maximum).ThedeviceexitsshutdownonceENABLEissettoahighlevel.Whenthedeviceis inshutdown,theloadisisolatedfromtheinput. 9.4.2 Short-CircuitProtection The TPS6014x devices are also short-circuit protected. The output current is limited to typically 100 mA during a hard short-circuit condition at the output; that is, when V is GND. In this case, the condition to enter the start- OUT up mode is met, the device stops switching and controls the on-resistance of the appropriate MOSFET switches tolimitthecurrent. 10 SubmitDocumentationFeedback Copyright©2000–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS60140 TPS60141

TPS60140,TPS60141 SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 www.ti.com 10.2.2 DetailedDesignProcedure 10.2.2.1 CapacitorSelection The capacitance values of the TPS6014x external capacitors are closely linked to the output current and output ripple requirements. For lowest ripple, low ESR (< 0.1 Ω) capacitors should be used at the input and output of thechargepump. The input capacitor improves system efficiency by reducing the input impedance. It also stabilizes the input current of the power source. The input capacitor should be chosen according to the power supply used and the distance from the power source to the converter IC. The input capacitor selection also depends on the output ripple requirements. C is recommended to be about 2-times to 4-times as large as the flying capacitors. The IN lowertheESRoftheinputcapacitorC ,theloweristheoutputripple. IN The output capacitor C can be selected from 2× to 50× larger than the flying capacitor, depending on the OUT rippletolerance.ThelargerC andtheloweritsESR,thelowerwillbetheoutputvoltageripple. OUT Generally, the flying capacitors will be the smallest. Only ceramic capacitors are recommended because of their low ESR and because they retain their capacitance at the switching frequency. Be aware that, depending on the material used to manufacture them, ceramic capacitors might lose their capacitance over temperature and voltage. Ceramic capacitors of type X7R or X5R material will keep their capacitance over temperature and voltage, whereas Z5U or Y5V-type capacitors will decrease in capacitance.

The first step is to increase the capacitance at the output. If the ripple is still too high, the second step would be to increase the capacitance at the input. For lower output currents, lower value flying capacitors can be used. Table 3 and Table4liststhemanufacturersofrecommendedcapacitors.

TPS60140,TPS60141 www.ti.com SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 11 Power Supply Recommendations The TPS6014x devices have no special requirements for its input power supply. The input power supply's output currentmustberatedaccordingtothesupplyvoltage,outputvoltageandoutputcurrentoftheTPS6014x. 12 Layout 12.1 Layout Guidelines Careful board layout is necessary due to the high transient currents and switching frequency of the converter. All capacitors should be soldered in close proximity to the IC. Connect ground and power ground terminals through a short, low-impedance trace. A PCB layout proposal for a two-layer board is given in Figure 19. The bottom layer of the board carries only ground potential for best performance. The layout also provides improved thermal performanceastheexposedleadframeofthePowerPADpackageissolderedtothePCB. An evaluation module for the TPS60140 is available and can be ordered under product code TPS60140EVM−144.TheEVMusesthelayoutshowninFigure19. 12.2 Layout Example NOTE: Actualsizeis15mmx25mm. Figure19.

Theycanbeomittedinmostapplications. 12.3 Power Dissipation The power dissipated in the TPS6014x depends mainly on input voltage and output current and is described by Equation5: P =I ´(3´V -V ) (DISS) O I O (5) Copyright©2000–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 15 ProductFolderLinks:TPS60140 TPS60141

TPS60140,TPS60141 SLVS273A–FEBRUARY2000–REVISEDNOVEMBER2015 www.ti.com Power Dissipation (continued) By observation of Equation 5, it can be seen that the power dissipation is worse for the highest input voltage V I andthehighestoutputcurrentI .Foraninputvoltageof3.6Vandanoutputcurrentof100mA,thecalculated OUT power dissipation P is 580 mW. This is also the point where the charge pump operates with its lowest (DISS) efficiency,whichisonly45%,andhencewiththehighestpowerlosses. P must be less than that allowed by the package rating. The thermal resistance junction to ambient of the (DISS) thermally enhanced TSSOP is 178°C/W for an unsoldered package. The thermal resistance junction to case, withtheexposedthermalpadsolderedtoaninfinitiveheatsink,is3.5°C/W. With the recommended maximum junction temperature of 125°C and an assumed maximum ambient operating temperature of 85°C, the maximum allowed thermal resistance junction to ambient of the system can be calculatedusingEquation6. T max-T 125°C-85°C R max = J A = =69°C/W qJA P max 580 mW (DISS) (6) Using a board layout as described in the application information section, R is typically 56°C/W for an θJA unsolderedPowerPAD™and41°C/WforasolderedPowerPAD. For more information, refer to the PowerPAD application report, PowerPAD™ Thermally Enhanced Package (SLMA002). 16 SubmitDocumentationFeedback Copyright©2000–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS60140 TPS60141
