NCP1252M

HGSEMI · Power Management - Specialized · SOP-8

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.
