ICL7660
Switched-capacitor voltage converter
PDF datasheet
       
NC 1  • 8 V+
CAP+ 2 7 OSC
GND 3 6 LV
CAP- 4 5 VOUT
       
Pin Symbol Description
1 NC no connection
2 CAP+ connection to + terminal of charge-pump capacitor
3 GND ground
4 CAP- connection to - terminal of charge-pump capacitor
5 VOUT negative voltage output
6 LV low voltage; connect to ground for V+ <3.5V
7 OSC oscillator control input
8 V+ positive supply voltage (1.5V to 10V)

Notes
  • Basic negative voltage converter: 10 µF capacitor across pins 2 and 4; 10 µF capacitor across pin 5 (negative lead) and ground (positive lead).

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
