NCP1236BD65R2G

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

NCP1236BD65R2G 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. Pull the pin up or down to latch off the controller; an internal current source allows direct connection of an NTC for over-temperature (OTP) detection. Absolute max ±10 mA, -0.3 to 10 V.
2 FB input Feedback input. Accepts an optocoupler collector to ground; controls the output regulation via the internal PWM comparator (internally divided by 5 with 20 kΩ pull-up to VFB(ref)).
3 CS input Current Sense input. Senses the primary MOSFET current for current-mode operation and offers overpower compensation adjustment via HV-derived offset. Absolute max -0.3 to 10 V.
4 GND power_in IC ground reference for all internal circuits and the driver return path.
5 DRV output Gate drive output for the external power MOSFET. ±500 mA peak source/sink capability with internal 13.5 V typical clamp. Absolute max -0.3 to 20 V, ±1000 mA.
6 VCC power_in Supply pin. Accepts up to 28 Vdc with overvoltage detection (VCC(ovp) ≈ 26.5 V). Powered by the internal HV startup source through Dynamic Self-Supply; UVLO turn-on ~12 V, turn-off ~9.5 V.
7 NC unconnected No connection. Pin 7 is removed/omitted on the SOIC-7 package to provide creepage clearance between VCC (pin 6) and HV (pin 8).
8 HV power_in High-voltage pin. Connects to the bulk capacitor or the rectified AC line to perform startup current sourcing, Dynamic Self-Supply, and brown-out detection. Absolute max -0.3 to 500 V.
