Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the controller. |
| 2 | FB | input | Feedback input; the PWM duty cycle is set by the voltage on this pin together with the current-sense signal at CS, with open-loop voltage 3.4 to 4.2 V and OLP threshold 3.0 to 3.6 V. |
| 3 | DEM | input | Multi-function pin: resistors from Vaux to ground set output OVP trigger (3.0 V typ), SCP trigger, brown-in/brown-out, line OVP trigger current and detect transformer demagnetization; absolute maximum -0.3 to 7 V. |
| 4 | CS | input | Current sense input; a series resistor to Rsense adjusts Vth_oc for OCP, and an NTC resistor via a diode from the auxiliary winding provides external OTP (0.30 V typ threshold); absolute maximum -0.3 to 7 V. |
| 5 | VCC | power_in | Power supply input, recommended 12 to 26 V, UVLO on 7.5 V typ and off 17 V typ, absolute maximum 32 V. |
| 6 | Gate | output | Totem-pole gate driver output for the power MOSFET, with 11 V typ output clamp voltage. |
