SC1460 - 5mA CAPLESSTM CHARGE PUMP

General Description

The SC1460 is a versatile charge pump designed for use in battery operated power supply applications requiring up to 5mA.

It enables a simple low current boost circuit to be implemented without the costly inductors or capacitors associated with regular switching circuits.

Key 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 popul.
