TL2575,TL2575HV www.ti.com SLVS638C–JANUARY2006–REVISEDNOVEMBER2014 9 Detailed Description 9.1 Overview The TL2575 and TL2575HV devices greatly simplify the design of switching power supplies by conveniently providing all the active functions needed for a step-down (buck) switching regulator in an integrated circuit. Acceptingawideinput-voltagerangeofupto60V(TL2575-HV)andavailableinfixedoutputvoltagesof3.3V,5 V, 12 V, 15 V, or an adjustable-output version, the TL2575 and TL2575HV devices have an integrated switch capable of delivering 1 A of load current, with excellent line and load regulation. The device also offers internal frequency compensation, a fixed-frequency oscillator, cycle-by-cycle current limiting, and thermal shutdown. In addition,amanualshutdownisavailableviaanexternal ON/OFFpin. The TL2575 and TL2575HV devices represent superior alternatives to popular three-terminal linear regulators. Due to their high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink is required. Optimized for use with standard series of inductors available from several different manufacturers, the TL2575 and TL2575HV greatly simplify the design of switch-mode power supplies by requiringaminimaladditionofonlyfourtosixexternalcomponentsforoperation. The TL2575 and TL2575HV devices are characterized for operation over the virtual junction temperature range of–40°Cto125°C. 9.2 Functional Block Diagram VIN Internal ON/OFF Unregulated On/Off DC Input 1 Regulator 5 + CIN FEEDBACK 4 Fixed-Gain R2 ErrorAmplifier Comparator 1-A + + Driver Switch _ R1 _ 1 kΩ OUTPUT L1 VOUT 2 + D1 COUT L O 1.23-V GND A Band-Gap 52-kHz Thermal Current 3 D Reference Oscillator Reset Shutdown Limit 3.3 V: R2 = 1.7 kΩ 5V:R2=3.1kΩ 12 V: R2 = 8.84 kΩ 15V:R2=11.3kΩ ADJ: R1 = Open, R2 = 0Ω PinnumbersarefortheKTT(TO-263)package.

For the adjustable version, FEEDBACK must be OUT connected between the two programming resistors. Again, both of these resistors should be in close proximity to theregulator,andeachshouldbelessthan100kΩtominimizenoisepickup. 9.3.2 ON/OFFInput ON/OFF should be grounded or be a low-level TTL voltage (typically < 1.6 V) for normal operation. To shut down the TL2575 or TL2575HV devices and place in standby mode, a high-level TTL or CMOS voltage should be supplied to this pin. ON/OFF should not be left open and safely can be pulled up to V with or without a pullup IN resistor. 9.4 Device Functional Modes 9.4.1 StandbyMode When a high-level TTL or CMOS voltage is applied to the ON/OFF pin, the device enters standby mode, drawing atypicalquiescentcurrentof50µA. 12 SubmitDocumentationFeedback Copyright©2006–2014,TexasInstrumentsIncorporated ProductFolderLinks:TL2575 TL2575HV

TL2575,TL2575HV SLVS638C–JANUARY2006–REVISEDNOVEMBER2014 www.ti.com Typical Application (continued) Output ripple of 50 mV to 150 mV typically can be achieved with capacitor values of 220 μF to 680 μF. Larger C can reduce the ripple 20 mV to 50 mV peak to peak. To improve further on output ripple, paralleling of OUT standard electrolytic capacitors may be used. Alternatively, higher-grade capacitors such as high frequency, low inductance,orlowESRcanbeused. ThefollowingshouldbetakenintoaccountwhenselectingC : OUT • At cold temperatures, the ESR of the electrolytic capacitors can rise dramatically (typically 3× nominal value at –25°C). Because solid-tantalum capacitors have significantly better ESR specifications at cold temperatures, they should be used at operating temperature lower than –25°C. As an alternative, tantalums canalsobeparalleledtoaluminumelectrolyticsandshouldcontribute10%to20%tothetotalcapacitance. • Low ESR for C is desirable for low output ripple. However, the ESR should be greater than 0.05 Ω to OUT avoid the possibility of regulator instability. Hence, a sole tantalum capacitor used for C is most OUT susceptibletothisoccurrence. • The ripple current rating of the capacitor, 52 kHz, should be at least 50% higher than the peak-to-peak inductorripplecurrent. 10.1.2.3 CatchDiode As with other external components, the catch diode should be placed close to the output to minimize unwanted noise. Schottky diodes have fast switching speeds and low forward voltage drops and, thus, offer the best performance, especially for switching regulators with low output voltages (V < 5 V). If a high-efficiency, fast- OUT recovery, or ultra-fast-recovery diode is used in place of a Schottky, it should have a soft recovery (versus abrupt turn-offcharacteristics)toavoidthechanceofcausinginstabilityandEMI.Standard50-to60-Hzdiodes,suchas the1N4001or1N5400series,arenotsuitable. 10.1.2.4 Inductor Proper inductor selection is key to the performance-switching power-supply designs. One important factor to consider is whether the regulator is used in continuous mode (inductor current flows continuously and never drops to zero) or in discontinuous mode (inductor current goes to zero during the normal switching cycle). Each mode has distinctively different operating characteristics and, therefore, can affect the regulator performance and requirements. In many applications, the continuous mode is the preferred mode of operation, since it offers greateroutputpowerwithlowerpeakcurrents,andalsocanresultinloweroutputripplevoltage.Theadvantages of continuous mode of operation come at the expense of a larger inductor required to keep inductor current continuous,especiallyatlowoutputcurrentsand/orhighinputvoltages. The TL2575 and TL2575HV devices can operate in either continuous or discontinuous mode. With heavy load currents,theinductorcurrentflowscontinuouslyandtheregulatoroperatesincontinuousmode.Underlightload, the inductor fully discharges and the regulator is forced into the discontinuous mode of operation. For light loads (approximately 200 mA or less), this discontinuous mode of operation is perfectly acceptable and may be desirable solely to keep the inductor value and size small. Any buck regulator eventually operates in discontinuousmodewhentheloadcurrentislightenough. The type of inductor chosen can have advantages and disadvantages. If high performance or high quality is a concern, then more-expensive toroid core inductors are the best choice, as the magnetic flux is contained completely within the core, resulting in less EMI and noise in nearby sensitive circuits. Inexpensive bobbin core inductors, however, generate more EMI as the open core does not confine the flux within the core. Multiple switching regulators located in proximity to each other are particularly susceptible to mutual coupling of magnetic fluxes from each other’s open cores. In these situations, closed magnetic structures (such as a toroid, pot core, orE-core)aremoreappropriate. Regardless of the type and value of inductor used, the inductor never should carry more than its rated current. Doing so may cause the inductor to saturate, in which case the inductance quickly drops, and the inductor looks like a low-value resistor (from the dc resistance of the windings). As a result, switching current rises dramatically (until limited by the current-by-current limiting feature of the TL2575 and TL2575HV devices) and can result in overheatingoftheinductorandtheICitself.

Typically about 1% of the output voltage, this ripple is due mainly to the inductorsawtoothripplecurrentandtheESRoftheoutputcapacitor(seeOutputCapacitor(C )).Furthermore, OUT the output also may contain small voltage spikes at the peaks of the sawtooth waveform. This is due to the fast switching of the output switch and the parasitic inductance of C . These voltage spikes can be minimized OUT throughtheuseoflow-inductancecapacitors. There are several ways to reduce the output ripple voltage: a larger inductor, a larger C , or both. Another OUT method is to use a small LC filter (20 μH and 100 μF) at the output. This filter can reduce the output ripple voltagebyafactorof10(seeFigure11). 10.1.2.6 Grounding The power and ground connections of the TL2575 and TL2575HV devices must be low impedance to help maintain output stability. For the 5-pin packages, both pin 3 and tab are ground, and either connection can be used as they are both part of the same lead frame. With the 16-pin package, all the ground pins (including signal and power grounds) should be soldered directly to wide PCB copper traces to ensure low-inductance connectionsandgoodthermaldissipation. 10.1.2.7 ReverseCurrentConsiderations There is an internal diode from the output to VIN.

Wiring and parasitic inductances, as well as stray capacitances, are subjected to rapidly switching currents, which can result in unwanted voltage transients. To minimize inductance and ground loops, the length of the leads indicated by heavy lines should be minimized. Optimal results can be achieved by single-point grounding (see Figure 11) or by ground-plane construction.

Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
