NCP1336BDR2G from onsemi, in a SOIC-13. 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 | OPP | input | Over Power Protection adjust. A negative voltage applied here reduces the internal maximum peak current setpoint. Connect via a resistor divider to an auxiliary winding for OPP compensation; ground to disable. Max negative operating voltage -300 mV. |
| 2 | OTP | input | Over-Temperature Protection input. Connect an NTC between this pin and GND; an internal current source biases the NTC. When the NTC pulls this pin down, the circuit permanently latches off. |
| 3 | Timer | passive | Fault timer duration select. Wiring a capacitor from this pin to ground sets the timer duration for fault handling. |
| 4 | ZCD | input | Zero Crossing / demagnetization Detection. Connected to the auxiliary winding (via a resistor) to detect the core reset event for quasi-resonant valley switching. Vmax -0.3 to +10 V DC, +12 V pulsed. |
| 5 | Ct | passive | Timing Capacitor. A capacitor from this pin to ground sets the frequency foldback timing (acts as the timing capacitor in foldback mode). |
| 6 | FB | input | Feedback pin. Connect the optocoupler collector here for output regulation via the internal pull-up. |
| 7 | CS | input | Current Sense input. Monitors the primary MOSFET peak current via the sense resistor for cycle-by-cycle current-mode control and OCP. |
| 8 | GND | power_in | Controller ground reference for all internal circuitry. |
| 9 | DRV | output | Gate driver output to the external power MOSFET. Peak source/sink capability -500 mA / +800 mA. Max voltage VCC + 1.0 V. |
| 10 | VCC | power_in | Supply pin for the controller, fed by the auxiliary winding after startup. Max continuous voltage 28 V, max current ±30 mA. |
| 11 | BO | input | Brownout input. Sensed against the bulk-rail resistor divider; stops circuit operation when mains input is too low. |
| 12 | OVP | input | Over-Voltage Protection input. Pulling this pin high permanently latches off the controller. |
| 13 | NC | unconnected | No connection. Pin is omitted from the package for improved creepage distance between HV (pin 14) and adjacent low-voltage pins. |
| 14 | HV | power_in | High-Voltage startup input. Connect to the bulk capacitor rail to power the internal high-voltage current source that delivers startup current to VCC. Voltage range -0.3 to 500 V. |
