GENERAL DESCRIPTION
The TC1225/1226/1227 are CMOS dual inverting charge pump voltage converters in 8-Pin MSOP packages. An on
board oscillator provides the clock, and only four external capacitors are required for full circuit implementation. Switch ing frequencies are 12kHz for the TC1225, 35kHz for the TC1226, and 125kHz for the TC1227.
FEATURES
■ Small 8-Pin MSOP Package
■ Operates from 1.8V to 5.5V
■ Up to 5mA Output Current at –VIN Pin
■ Up to 1mA Output Current at –2VIN Pin
■ –VIN and –2VINOutputs Available
■ Low Supply Current
