VPS2107 from VPSC, in a ESOP8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | COM | input | SSR-mode optocoupler feedback pin; its voltage sets the peak current and switching frequency, with internal RC compensation so it connects directly to an optocoupler, and it is left floating in PSR mode. |
| 2 | VDD | power_in | Supply pin that feeds an internal LDO (VCC 5.3 V in linear operation, about 0.3 V dropout); VDD clamps at about 10 V, and if the clamp sinks more than 5.3 mA the power switch is disabled into self-recovering protection. |
| 3 | VCS | input | Peak-current threshold setting pin, connected through a resistor of tens of kΩ to GND, which sets the maximum and minimum peak current of the lossless current sensing (PSR mode). |
| 4 | GND | power_in | Reference ground for the control logic and the source of the internal LDMOS power switch. |
| 5 | DRN | output | Drain of the internal 132 V / 0.6 Ω LDMOS power switch (absolute maximum DRN-to-GND voltage -1.3 V to 132 V). |
| 6 | RIN | input | Connects through an external resistor to VIN to set startup, power-switch turn-off speed and feedforward compensation; absolute maximum voltage to GND is -0.3 V to 35 V and recommended resistor is 1 MΩ or less (typically hundreds of kΩ). |
| 7 | OUP | input | Multiplexed input over/under-voltage protection pin, where a divider ratio sets the undervoltage thresholds (about 2.0 V on, 1.75 V off) and a divider resistance sets the overvoltage threshold; absolute maximum is -0.3 V to 6 V. |
| 8 | FB | input | Output voltage feedback pin sensing the output via an auxiliary winding (PSR) or a resistor divider (buck, boost, flyback non-isolated); absolute maximum is -0.5 V to 6 V and it must be tied to GND in SSR mode. |
| 9 | EP | power_in | Exposed thermal pad internally connected to GND, to be soldered to a large ground area for heat dissipation; the datasheet states it is not used as an electrical connection point. |
