FP6385S6CTR

Fitipower Integrated Tech · DC-DC Converters · SOT-23-6

FP6385S6CTR from Fitipower Integrated Tech, in a SOT-23-6. 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 EN input Enable control: pull high to turn the IC on and low to disable it; do not leave this pin floating.
2 GND power_in Ground.
3 LX output Power switching node connecting the inductor to the drains of the internal high-side PMOS and low-side NMOS.
4 VIN power_in Power supply input (2.7V to 6V); place input capacitors as close as possible from VIN to GND to avoid noise influence.
5 PG output Open-drain power good output that requires a pull-up resistor and is released when the output rises above 90% of nominal regulation.
6 FB input Feedback input connected to VOUT through a resistive divider; the IC regulates this pin at 0.6V.
