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 | NC | unconnected | No connection. Datasheet recommends grounding this pin in the application circuit. |+| 2 | CAP+ | passive | Positive terminal of the external flying (pump) capacitor. Connect a 10 uF capacitor between CAP+ (pin 2) and CAP- (pin 4). |+| 3 | GND | power_in | Ground reference for the device and for the input/output capacitors. |+| 4 | CAP- | passive | Negative terminal of the external flying (pump) capacitor. Connect a 10 uF capacitor between CAP+ (pin 2) and CAP- (pin 4). |+| 5 | VOUT | power_out | Inverted charge-pump output. Delivers a negative voltage of approximately -VDD (range -2.5 V to -11 V). Bypass to GND with a 10 uF storage capacitor. Typical output resistance 50 Ω at VIN=5 V, IOUT=10 mA. |+| 6 | NC | unconnected | No connection. Datasheet recommends grounding this pin in the application circuit. |+| 7 | OSC | bidirectional | Oscillator node. Left open the internal oscillator runs at ~10 kHz. May be pulled by an external CMOS clock (through a 1 kΩ series resistor) to raise frequency (charge-pump runs at half the clock), or loaded with an external capacitor between OSC (pin 7) and VDD (pin 8) to lower the oscillator frequency and reduce switching loss. |+| 8 | VDD | power_in | Positive supply input. Operating range 2.5 V to 11 V (absolute maximum 11.5 V). Bypass to GND with a 10 uF capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TOPPOWER Nanjing Extension Microelectronics |+| Package | SOIC-8-150mil |+| Category | PMIC |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TP7660H`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TOPPOWER Nanjing Extension Microelectronics datasheet](docs/tp7660h-datasheet.pdf) (7 pp, sha256 `c4c325621b63dab9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
