EX9610PD from Existar, 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 | NC | unconnected | No connection. Floating pin, no electrical function. Leave open on the PCB. |
| 2 | VDD | power_in | Chip supply pin. Fed from the internal 150V JFET self-supply through an LDO regulated to 7.7V typ (7.5-7.9V, with CVDD=1uF, HV=40V). Startup threshold 7.4V, UVLO 5.3V, clamp 8.3V. Requires a 1uF ceramic cap to S (GND) placed close to the pin. |
| 3 | S | power_in | Source of the internal power MOSFET and ground reference for the control die. Pins 3 and 4 are internally tied - both must be connected to the low-side (output-side) net with a low-impedance path. |
| 4 | S | power_in | Source of the internal power MOSFET and ground reference for the control die. Internally tied to pin 3. |
| 5 | D | power_in | Drain of the internal 100V / 15mΩ SGT MOSFET and high-voltage sense / self-supply input. Pins 5, 6, 7, 8 are internally tied - parallel them and route close to the transformer secondary to minimise conduction and switching-node loss. Absolute max −0.3 to 100V; recommended operating <100V. |
| 6 | D | power_in | Drain of the internal power MOSFET / HV sense. Internally tied to pins 5, 7, 8. |
| 7 | D | power_in | Drain of the internal power MOSFET / HV sense. Internally tied to pins 5, 6, 8. |
| 8 | D | power_in | Drain of the internal power MOSFET / HV sense. Internally tied to pins 5, 6, 7. |
