NJU7660A

NJU7660A VOLTAGE CONVERTER  GENERALDESCRIPTION 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.  PACKAGE OUTLINE NJU7660AM NJU7660AV  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)  High-efficiency voltage conversion rate :+3.0V to +10V(for Twofold voltage converter) :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 18 27 36 45 NJU7660AM NJU7660AV PIN FUNCTION 1.
