TL7660IDR from Texas Instruments, in a SOIC-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+ | output | Positive terminal of external charge pump capacitor C1 connected to pin 4 (CAP−) for switched-capacitor voltage conversion operation. |
| 3 | GND | power_in | Ground reference and return path for device circuits and external loads. |
| 4 | CAP− | output | Negative terminal of external charge pump capacitor C1 connected to pin 2 (CAP+) for switched-capacitor voltage conversion operation. |
| 5 | VOUT | output | Negative output voltage terminal generating output voltage with magnitude equal to positive input supply voltage (1.5 V to 10 V input produces −1.5 V to −10 V output) with typical conversion efficiency up to 99.9% at open circuit. |
| 6 | LV | input | Low voltage mode control input; tie to GND for VIN < 3.5 V to enable low-voltage operation by bypassing internal series regulator, or leave floating for VIN ≥ 3.5 V to prevent device latchup. |
| 7 | OSC | bidirectional | Oscillator control terminal with internal RC oscillator operating at nominal 10 kHz (VCC = 5 V), tunable by adding capacitor to ground for lower frequency or override by external clock input with 1 kΩ series resistor for higher frequency. |
| 8 | VCC | power_in | Positive supply voltage input with recommended operating range 1.5 V to 10 V for full device functionality from −40°C to 125°C. |
