VPS8703 from VPSC, in a ESOP-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 | CLK | input | Oscillator clock adjustment input; floating state gives 250 kHz default; external resistor to GND adjusts frequency. |
| 2 | GND | power_in | Logic circuit and analog circuit ground. |
| 3 | VCC | power_in | Power supply input; requires 1uF bypass capacitor to GND placed close to device. |
| 4 | EN | input | Active-low enable/disable input; device enabled when high or floating, disabled when low. |
| 5 | VD2 | output | Transformer driver output 2. |
| 6 | NC | unconnected | No function pin. |
| 7 | NC | unconnected | No function pin. |
| 8 | VD1 | output | Transformer driver output 1. |
| 9 | EP | power_in | Exposed thermal pad internally connected to GND; solder to large ground area for enhanced heat dissipation. |
