NJU7660AM-TE1

NJU7660A VOLTAGE CONVERTER GENERAL DESCRIPTION PACKAGE OUTLINE 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 = -V ) converter OUT IN requires only two capacitors, and positive twofold voltage(V =2V ) OUT IN NJU7660AM NJU7660AV converter requires two capacitors and two diodes as external components. FEATURES Full Compatible with NJU7660 Correspond to MLCC and electrolytic capacitor Twofold positive Output Polarity-converted Negative voltage Output Operating voltage range :+1.5V to +10V(for Negative voltage converter) :+3.0V to +10V(for Twofold voltage converter) High-efficiency voltage conversion rate :99.9%(No load, Negative voltage converter) Few external components :2 capacitors(Negative voltage converter) :2 capacitors, 2diode(Twofold voltage converter) Package Outline :DMP8, SSOP8 CMOS Technology PIN CONFIGURATION PIN FUNCTION 1 8 1.
