NCP1236AD100R2G

onsemi · AC-DC Controllers And Regulators · SOIC-7

NCP1236AD100R2G from onsemi, in a SOIC-7. 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 LATCH input Latch-off input. Pulling this pin up or down latches off the controller. An internal current source allows direct connection of an NTC thermistor for over-temperature protection (OTP). Also used for severe fault detection.
2 FB input Feedback input. An optocoupler collector connected to ground controls the output regulation loop. Internally pulled up through a 20 kΩ resistor to VFB(ref); divided by 5 for the PWM comparator.
3 CS input Current sense input. Senses the primary MOSFET current for current-mode operation via an external sense resistor. Provides overpower compensation adjustment and includes leading-edge blanking (tLEB).
4 GND power_in IC ground reference for all internal circuitry and the return path for the DRV output stage.
5 DRV output Gate drive output for the external power MOSFET. ±500 mA peak source/sink drive capability with internal clamp; absolute max −0.3 to 20 V, ±1000 mA.
6 VCC power_in Controller supply input. Accepts up to 28 Vdc with internal overvoltage detection (VCC OVP). Supplied either from an auxiliary winding or from the internal Dynamic Self-Supply (DSS) sourced through the HV pin.
8 HV power_in High-voltage input. Connects to the bulk capacitor or the rectified AC line and performs start-up current source, Dynamic Self-Supply (DSS), brown-out detection and overpower/HV-sense functions. Absolute max −0.3 to 500 V, ±20 mA.
