NCP12400CBAAB0DR2G 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 | FAULT | input | Fault input: pull the pin high or low to stop the controller. An internal current source allows direct connection of an NTC for over-temperature detection. Device restarts in autorecovery mode or latches off depending on the option. |
| 2 | FB | input | Feedback + Shutdown pin. An optocoupler tied to ground controls output regulation. Pulling the FB pin to GND puts the part in low-consumption Off mode. |
| 3 | CS | input | Current Sense input for cycle-by-cycle primary peak-current mode control. Also provides overpower compensation adjustment and implements over-voltage protection. |
| 4 | GND | power_in | Controller ground reference for all internal circuitry and the DRV return path. |
| 5 | DRV | output | Gate drive output to the external primary-side power MOSFET. 300 mA source / 500 mA sink peak drive capability. |
| 6 | VCC | power_in | Controller supply pin, connected to the external auxiliary winding. Accepts up to 28 Vdc with internal over-voltage detection; also served by the internal Dynamic Self-Supply from the HV pin during start-up and light-load conditions. |
| 8 | HV | power_in | High-Voltage pin connected to the rectified AC line. Provides start-up current-source, Dynamic Self-Supply, brown-out detection, X2 capacitor discharge, and HV sensing for overpower protection. Must NOT be connected to a DC voltage. |
