NJU7660A
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 (V_OUT= -V_IN) converter
requires only two capacitors, and positive twofold voltage(V_OUT=2V_IN)
converter requires two capacitors and two diodes as external components.
