DESCRIPTION
The SC1460 is a versatile charge pump designed for
use in battery operated power supply applications re-
quiring up to 5mA. It enables a simple low current
boost circuit to be implemented without the costly in-
ductors or capacitors associated with regular switching
circuits. Features include internal MOSFETs, control
circuitry and charge pump capacitor, requiring only two
external capacitors for a total solution. With a very
high operating frequency (8MHz free running at 2.5V in
typically), the SC1460 does not require large input or
output capacitors, and therefore uses very little board
space. Two versions of the SC1460 are available: the
-3.3 produces a regulated 3.3V output from 2.5V in,
and the -5.0 produces a regulated 5V output from 3.3V
in. It is supplied in the popular 3 lead, SOT-23 pack-
age.
FEATURES
Small size - SOT-23 package
4% voltage accuracy
Typical 100uA quiescent current
