ICL7660SIBAZ from RENESAS, 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 | BOOST | input | Frequency Boost pin; connecting it to V+ raises the oscillator frequency by about 3.5 times (35kHz typ vs 10kHz typ with pin open or at GND), which lowers output impedance and ripple. |
| 2 | CAP+ | passive | Positive terminal of charge-pump capacitor C1; the + terminal of a polarized C1 must connect here. |
| 3 | GND | power_in | Ground; the + terminal of reservoir capacitor C2 connects here, and VOUT must not go more positive than this pin or device latch-up will occur. |
| 4 | CAP- | passive | Negative terminal of charge-pump capacitor C1; an external Schottky diode from VOUT to this pin may be needed to prevent latchup when the input is above 5V with a rise rate over 2V/µs. |
| 5 | VOUT | power_out | Negative voltage output (-V+), connected to the negative side of reservoir capacitor C2; must not go more positive than GND. |
| 6 | LV | input | Low-voltage pin; tie to GND for supply voltages below 3.5V to bypass the internal regulator, and leave open for 3.5V to 12V to prevent latchup. |
| 7 | OSC | input | Oscillator terminal; an external capacitor lowers the oscillator frequency (nominal 10kHz at 5V), or it can be overdriven by an external clock through a 1k series resistor. |
| 8 | V+ | power_in | Positive supply input, operating range 1.5V to 12V (absolute maximum 13.0V). |
