Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Chip power supply pin: VCC startup voltage is 17.5-20.5 V (rising), UVLO is 8.5-10.5 V (falling), OVP is 23-27 V, the clamp is 30-33 V at 10 mA, and the absolute maximum VCC is 35 V. |
| 2 | GND | power_in | Chip ground reference pin; the datasheet states no electrical limit for this pin. |
| 3 | FB | input | Output voltage feedback pin sampling the auxiliary winding; the constant-voltage reference is 1.97-2.03 V (2.0 V typical), the output short threshold is 1.16 V, and the absolute maximum voltage is -0.3 to 7 V. |
| 4 | CS | input | Current sense pin for the sense resistor Rs; the constant-current sense threshold is 588-612 mV (600 mV typical), the leading-edge blanking time is 500 ns, and the absolute maximum voltage is -0.3 to 7 V. |
| 5 | D | passive | Internal power MOSFET drain (pins 5-8 are internally connected); the drain voltage rating is 650 V (absolute maximum -0.3 to 650 V), and Rdson is 2 Ω for the GP8242H at 1 A. |
