Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin. |
| 2 | FB | input | Feedback input pin; PWM duty cycle is determined by the voltage level into this pin and the CS current-sense signal, with over load protection threshold VFB_OLP of 4.0 to 4.8V and absolute maximum of -0.3 to 7V. |
| 3 | DMAG | input | Demagnetization input that senses input and output voltages from the auxiliary winding, with absolute maximum of -0.3 to 7V and valley detection at 85mV falling. |
| 4 | CS | input | Current sense pin, connect resistors to ground; absolute maximum -0.3 to 7V with 300ns leading edge blanking and 0.5V typical zero-duty current limit threshold. |
| 5 | VDD | power_in | Power supply pin with recommended range 10-48V, absolute maximum 60V, UVLO on 7.2V and off 16.5V typical. |
| 6 | GATE | output | Gate driver output for the external MOSFET, clamped at 11.5V typical. |
