TPS563231DRLR

Texas Instruments · DC-DC Converters · SOT-563

TPS563231DRLR from Texas Instruments, in a SOT-563. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input voltage supply pin, drain of high-side NFET; operating range 4.5 V to 17 V.
2 SW output Switch node connection between high-side NFET and low-side NFET.
3 GND power_in Power ground terminal connected to source of low-side FET internally.
4 BST power_out Bootstrap supply for high-side NFET gate driver; connect 0.1 µF capacitor between BST and SW pins.
5 EN input Enable input control with hysteresis; high level 1.10 to 1.42 V enables operation, low level 1.00 to 1.30 V disables; do not leave floating.
6 FB input Converter feedback input for voltage regulation with internal reference voltage 600 mV.
