TC1240A
Positive Unregulated Doubling Charge
Pump with Shutdown in a SOT-23 Package
TC1240A-1 11/03/00
Positive Doubling Charge Pump with Shutdown in a SOT-23
Package
GENERAL DESCRIPTION
The TC1240A is a doubling CMOS charge-pump volt-
age converter in a small 6-Pin SOT-23A package. TC1240A
doubles an input voltage which can range from +2.5V to
+5.5V. Conversion efficiency is typically >99%. Internal
oscillator frequency is 160kHz. The TC1240A has an active
high shutdown which limits the current consumption of the
device to less than 1
A.
External component requirement is only two capacitors
for standard voltage doubler applications. All other circuitry,
including control, oscillator, power MOSFETs are integrated
on-chip. Typical supply current is 550
A and the device is
available in a 6-Pin SOT-23A surface mount package.
