TPS54308DDCT

Texas Instruments · DC-DC Converters · TSOT-23-6

TPS54308DDCT from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin for low-side NFET source and control circuit; provides reference for output voltage feedback.
2 SW output Switch node connection between high-side and low-side NFET; rated -5V to 30V at 20ns transient voltage.
3 VIN power_in Input power supply pin rated 4.5V to 28V; drain terminal of high-side power NFET.
4 FB input Converter feedback input connected via external resistor divider to output voltage; internal reference voltage 0.596V nominal.
5 EN input Enable control pin with internal pull-up current; device enables when EN > 1.28V rising threshold, disables when EN < 1.19V falling threshold.
6 BOOT output Bootstrap supply for high-side NFET gate driver circuit; connect 0.1µF ceramic capacitor between BOOT and SW pins for proper operation.
