| Pin Number | Pin Name | Description / Key Function | | :--- | :--- | :--- | | | GND / S / Source | The ground reference pin for both the control circuit and the power section. It is the source connection of the internal power MOSFET. | | 2 | Vcc | The power supply pin for the IC's internal control circuit. It is connected to an external startup resistor and an auxiliary winding of the transformer. | | 3 | FB / OCP / Feedback | A multi-function pin. It receives the feedback signal from the secondary side (via an optocoupler) to regulate the output voltage. It also serves as the overcurrent protection (OCP) sense input. | | 4 | CS / Current Sense | The current sense pin. It monitors the current flowing through the internal power MOSFET by sensing the voltage across an external sense resistor. | | 5 | Drain | The drain pin of the internal high-voltage power MOSFET. This pin is connected to the primary winding of the switching transformer. |
: Built-in to reduce electromagnetic interference (EMI) noise, simplifying compliance with regulatory standards.
