VOLTAGE CONVERTER

 GENERAL DESCRIPTION

NJU7660A is a CMOS switched capacitor, voltage converter

designed to be an Improved direct replacement of popular 7660/1044.

NJU7660A provides several voltage conversion functions.

The application circuit of negative voltage (VOUT= -VIN) converter

requires only two capacitors, and positive twofold voltage(VOUT=2VIN)

converter requires two capacitors and two diodes as external components.
