NCP1403

15 V/50 mA PFM Step−Up

DC−DC Converter

The NCP1403 is a monolithic PFM step−up DC−DC converter. This

device is designed to boost a single Lithium or two cell AA/AAA

battery voltage up to 15 V (with internal MOSFET) output for

handheld applications. A pullup Chip Enable feature is built with this

device to extend battery−operating life. Besides, the device can also be

incorporated in step−down, and voltage−inverting configurations.

This device is available in space−saving TSOP−5 package.
