NCP1406

25 V/25 mA PFM Step−Up

DC−DC Converter

The NCP1406 is a monolithic PFM step−up DC−DC converter.

This device is designed to boost single Lithium or two cells AA/AAA

battery voltage up to 25 V (with internal MOSFET) output for

handheld applications. A pullup Chip Enable feature is built−in with

this device to extend battery−operating life. In addition to standard

boost converter topologies, this device can be configured for

voltage−inverting and step−down applications. This device is

available in space−saving TSOP−5 package. With its small footprint,

the device is also ideal for generating a boosted voltage from a 3.3 V

or 5.0 V power rail.
