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.
These devices provide both a negative voltage inversion
(available at the –VIN output) and a negative doubling
voltage inversion (available at the –2 VIN output), with a low
output impedance capable of providing output currents up to
5mA for the –VIN output and 1mA for the –2VIN output. The
input voltage can range from +1.8V to +5.5V.
