AP63300WU-7

Diodes Incorporated · DC-DC Converters · TSOT-23-6

AP63300WU-7 from Diodes Incorporated, in a TSOT-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 FB input Feedback sensing terminal for the output voltage, connected to the output resistive divider; the internal reference is 0.8V ±1%.
2 EN input Digital enable input that turns the regulator on above a 1.18V threshold and off below 1.09V; it can connect to VIN or float for automatic startup and also sets the UVLO thresholds.
3 VIN power_in Power input supplying the IC and the step-down power MOSFETs, to be driven from 3.8V to 32V and bypassed to GND with a suitably large capacitor.
4 GND power_in Power ground.
5 SW output Power switching output, the switching node that feeds the output LC filter and load.
6 BST input High-side gate drive boost input; a 100nF ceramic capacitor is recommended from BST to SW to power the high-side driver.
