TC7660M from HGSEMI, in a SOP-8. 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 | NC | unconnected | No connection; the datasheet lists this pin as not connected. |
| 2 | CAP+ | passive | Positive terminal of the external pump capacitor C1, charged to V+ during the first half cycle. |
| 3 | GND | power_in | Ground pin. |
| 4 | CAP- | passive | Negative terminal of the external pump capacitor C1, shifted to -V+ during the second half cycle. |
| 5 | Vout | power_out | Negative voltage output (nominally -V+); do not short the output to V+ above 5.5V for extended periods. |
| 6 | LV | input | Low-voltage selection pin: connect to GND to disable the internal regulator for better low-voltage operation, and leave open for supply voltages above 3.5V. |
| 7 | OSC | passive | Oscillator pin: left open for the nominal 10 kHz frequency, or connect an external capacitor to ground to lower the oscillator frequency. |
| 8 | V+ | power_in | Positive supply input, 2.5V to 9V operating range (absolute maximum input voltage +9V). |
