ICL7660SIBAZT

RENESAS · Charge Pumps · SOIC-8

ICL7660SIBAZT from RENESAS, in a SOIC-8. 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 BOOST input Frequency boost input; connect to V+ to increase oscillator frequency by √3 to reduce output impedance and ripple with smaller capacitors, or leave floating for nominal 10kHz operation.
2 CAP+ passive Pump capacitor positive terminal; connect positive terminal of external capacitor C1 (10µF to 100µF) for charge pump switching node.
3 GND power_in Ground; negative reference connection and return path for output voltage and reservoir capacitor C2.
4 CAP- passive Pump/reservoir capacitor junction node; internal switching connection between pump capacitor C1 and reservoir capacitor C2, voltage nominally -V+ under load.
5 VOUT output Voltage output; generates negative output voltage from -1.5V to -12V (inverse of V+ input) with output impedance of 60-100Ω at 20mA load; requires external reservoir capacitor C2.
6 LV input Low voltage control input; tie to GND for V+ <3.5V to bypass internal regulator for improved low-voltage operation, or leave floating for V+ ≥3.5V to maintain latchup protection.
7 OSC input Oscillator control terminal; connect external capacitor to reduce oscillator frequency (100pF lowers from 10kHz to 1kHz), or apply external clock with 1kΩ series resistor to override frequency.
8 V+ power_in Positive supply voltage input; accepts 1.5V to 12V with absolute maximum of 13V; provides power to charge pump with supply current 80-160µA typical at 25°C and 5V.
