# TL7660IDGKR

**Texas Instruments** · DC-DC Converters · VSSOP-8-0.65mm

TL7660IDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 within device. |
| 2 | CAP+ | passive | Pump capacitor positive terminal; connect 10 µF typical capacitor for switched-capacitor charge pump function. |
| 3 | GND | power_in | Ground reference potential and return path for all circuits. |
| 4 | CAP− | passive | Charge reservoir capacitor negative terminal; connect 10 µF typical capacitor for output voltage and ripple filtering. |
| 5 | VOUT | output | Negative output voltage nominally equal to −VIN in converter mode, or positive doubled output (2VIN − 2VF) with external diodes in doubler mode. |
| 6 | LV | input | Low voltage mode control; tie to GND for VCC < 3.5 V to bypass internal voltage regulator, leave floating for VCC ≥ 3.5 V to prevent device latchup. |
| 7 | OSC | input | Oscillator frequency control terminal; connect capacitor to ground to reduce internal 10 kHz nominal frequency or drive with external clock source to override oscillator. |
| 8 | VCC | power_in | Positive supply voltage input operating range 1.5 V to 10 V; supply for internal circuits and source for charge pump. |
