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. |
