VPS8703B from VPSC, in a ESOP8. 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 | External clock input and dead-zone time adaptive mode selection; when floating, internal pull-up selects 250 kHz fixed dead-zone; when tied to GND, enables adaptive dead-zone mode; accepts external clock for synchronization. |
| 2 | GND | power_in | Ground reference for logic and analog circuits. |
| 3 | VIN | power_in | Power supply input, 6-30V nominal; bypass with 1 µF ceramic capacitor placed adjacent to device pins. |
| 4 | EN | input | Active-high logic enable; pulling to low stops chip operation and enables ultra-low standby mode (~19 µA); floating defaults to high via internal pull-up. |
| 5 | VD2 | output | Bridge leg 2 transformer drive output (complementary to VD1); peak drain current 1.6 A absolute maximum, rated for VIN+0.3 V. |
| 6 | NC | unconnected | No internal connection; may be left unconnected or tied to ground. |
| 7 | NC | unconnected | No internal connection; may be left unconnected or tied to ground. |
| 8 | VD1 | output | Bridge leg 1 transformer drive output (complementary to VD2); peak drain current 1.6 A absolute maximum, rated for VIN+0.3 V. |
| 9 | EP | power_in | Exposed thermal pad internally bonded to GND; not used as primary electrical connection but must be soldered to large ground plane to enhance heat dissipation. |
