NCP1252M from HGSEMI, in a SOP-8. 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 | FB | input | Feedback input with 40kΩ input impedance and 3.5kΩ internal pull-up resistor; burst mode entry threshold 0.3V, exit at 0.33V, power limiting threshold 4.6V. |
| 2 | BO | input | Brown-out input monitoring input voltage image with 1.00V threshold and 10µA hysteresis current source for protection against low input voltage. |
| 3 | CS | input | Current sense input connected through resistor to GND, with 1.0V overcurrent threshold, 160ns leading edge blanking, and 26.5kΩ internal ramp compensation resistance. |
| 4 | RI | input | Frequency programming input; resistor to ground sets switching frequency from 50kHz to 500kHz maximum. |
| 5 | GND | power_in | Ground reference connection point. |
| 6 | GATE | output | Totem-pole gate driver output for power MOSFET with ±500mA/±800mA source/sink capability, 15-18V voltage clamping, and 45ns/30ns rise/fall times into 1000pF load. |
| 7 | VDD | power_in | IC DC power supply input with 10-26V operating range, 11.7V startup threshold, 9.0V shutdown threshold, and 30V absolute maximum rating. |
| 8 | SS | input | Soft-start input pin; external capacitor to ground programs soft-start ramp with 10µA charging current and 4.0V completion voltage threshold. |
