TC7660SEOA713 from Microchip Tech, in a SOIC-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 | BOOST | input | Frequency boost control pin; connect to V+ to increase switching frequency from 10 kHz to 45 kHz, otherwise leave open or connect to ground. |
| 2 | CAP+ | passive | Positive terminal for external charge pump flying capacitor; recommended to use low ESR capacitor for efficient charge transfer. |
| 3 | GND | power_in | Ground terminal serving as input and output zero volt reference. |
| 4 | CAP- | passive | Negative terminal for external charge pump flying capacitor; proper polarity is imperative when using polarized capacitors. |
| 5 | VOUT | output | Output voltage terminal supplying negative DC voltage; charge pump output capacitor positive terminal connects here for output filtering. |
| 6 | LV | input | Low voltage control pin ensuring oscillator operation below 3.5V input; connect to GND for V+ < 3.5V, otherwise leave open to prevent damage. |
| 7 | OSC | input | Oscillator control input for frequency modification; bypass with external capacitor to slow oscillator or apply external clock with 1 kΩ series resistor. |
| 8 | V+ | power_in | Positive power supply input accepting 1.5V to 12V for inverting voltage conversion; bypass to ground with low ESR capacitor. |
