ICL7660ACBAZA

RENESAS · DC-DC Converters · SOIC-8

ICL7660ACBAZA 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 NC unconnected No connection on the ICL7660A (this is the BOOST pin only on the ICL7660S).
2 CAP+ passive Positive terminal of the charge-pump capacitor C1, whose + terminal must connect here when using polarized capacitors.
3 GND power_in Ground; the + terminal of reservoir capacitor C2 connects here, and the output (pin 5) must not go more positive than GND or latch-up will occur.
4 CAP- passive Negative terminal of the charge-pump capacitor C1; an external Schottky diode from VOUT to CAP- may be needed to prevent latchup when the input is above 5V with a rise rate over 2V/µs.
5 VOUT power_out Negative output voltage (-1.5V to -12V for a 1.5V to 12V input) connected to reservoir capacitor C2.
6 LV input Low-voltage control: tie to GND to bypass the internal regulator for supplies below 3.5V, and leave open for supplies above 3.5V to ensure latchup-proof operation.
7 OSC input Oscillator terminal: nominal 10kHz at 5V, can be lowered with an external capacitor or overdriven by an external clock through a 1k series resistor.
8 V+ power_in Positive supply input, 1.5V to 12V operating range (13.0V absolute maximum).
