GP7596A

HaloChip · Synchronous Rectifier Controllers · SOP-8

GP7596A from HaloChip, in a SOP-8. 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 GND power_in Chip ground. Return for the internal control logic and driver, and source of the internal power MOSFET (floating-ground / GP7596X pinout variant).
2 GND power_in Chip ground. Tied internally to pins 1 and 3; parallel these pins to the ground plane to reduce inductance to the MOSFET source.
3 GND power_in Chip ground. Tied internally to pins 1 and 2.
4 VCC power_in Chip supply pin, nominally 5 V (UVLO on 3.7 V, UVLO off 2.8 V, internally clamped to 6 V at 20 mA). Place a bypass capacitor (typ. 1 µF) close to this pin; the internal HV LDO charges VCC from SW/SWS so no auxiliary winding is needed.
5 SW power_out Drain of the integrated synchronous-rectifier power MOSFET. Operating drain-source voltage rated to 65 V (recommended 4.7-60 V); RDS(on) 18 mΩ for the GP7596A. Tie pins 5-8 in parallel to carry the SR current with minimum resistance.
6 SW power_out Drain of the integrated power MOSFET. Tied internally to pins 5, 7, 8.
7 SW power_out Drain of the integrated power MOSFET. Tied internally to pins 5, 6, 8.
8 SW power_out Drain of the integrated power MOSFET. Tied internally to pins 5, 6, 7.
