HaloChip · Synchronous Rectifier Controllers · SOP-8

GP7596B 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. Tied together internally with pins 2 and 3. Used as the return for the internal control logic in the 'floating-ground' SR architecture.
2 GND power_in Chip ground. Tied together internally with pins 1 and 3.
3 GND power_in Chip ground. Tied together internally with pins 1 and 2.
4 VCC power_in Chip supply, nominally 5 V (abs-max 6 V, clamp ~6 V @ 20 mA). Bypass locally with ~1 µF. Fed by the internal HV LDO from SW, so no auxiliary winding is needed. UVLO(ON)=3.7 V, UVLO(OFF)=2.8 V.
5 SW power_out Drain of the internal synchronous-rectifier power MOSFET. Tied together internally with pins 6, 7 and 8 to carry the SR current. Absolute-max 65 V, recommended 4.7-60 V, 15 A continuous / 30 A pulsed.
6 SW power_out Drain of the internal SR power MOSFET (tied to pins 5, 7, 8).
7 SW power_out Drain of the internal SR power MOSFET (tied to pins 5, 6, 8).
8 SW power_out Drain of the internal SR power MOSFET (tied to pins 5, 6, 7). Also feeds the internal HV LDO that generates VCC.
