Positive Doubling Charge Pump with Shutdown

in SOT Package

GENERAL DESCRIPTION

FEATURES

The TC1240 is a doubling CMOS charge-pump voltage

converter in a small 6-Pin SOT-23A package. TC1240

doubles an input voltage which can range from +2.5V to

+4.0V. Conversion efficiency is typically >99%. Internal

oscillator frequency is 160kHz for the TC1240. The TC1240

has an active high shutdown which limits the current con-

sumption of the device to less than 1µA.

External component requirement is only two capacitors

for standard voltage doubler applications. All other circuitry,

includingcontrol, oscillator, powerMOSFETsareintegrated

on-chip. Typical supply current is 180µA and the device is

available in a 6-Pin SOT-23A surface mount package.
