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.
