TL7660CDGKR from Texas Instruments, in a VSSOP-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 internal connection. |
| 2 | CAP+ | passive | Positive terminal of pump capacitor, typically connected to a 10 µF capacitor for charge pump function. |
| 3 | GND | power_in | Ground reference, system common and negative supply rail. |
| 4 | CAP− | passive | Negative terminal of reservoir capacitor; typically connected to 10 µF capacitor for output filtering. |
| 5 | VOUT | output | Output voltage terminal producing negative voltage conversion of input supply, range -1.5 V to -10 V. |
| 6 | LV | input | Low voltage control input; tie to GND for VCC < 3.5 V to bypass regulator, leave floating for VCC > 3.5 V to prevent latchup. |
| 7 | OSC | input | Oscillator terminal with nominal 10 kHz frequency at VCC = 5 V; external capacitor reduces frequency, external clock increases frequency. |
| 8 | VCC | power_in | Positive power supply input with operating range of 1.5 V to 10 V. |
