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. |
