Semtech Corporation SC1460
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. 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.| Part No. | SC1460 |

DESCRIPTION
FEATURES
include internal MOSFETs, control circuitry and charge pump capacitor, requiring only two external capacitors for a total solution. 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 package.FEATURES
