NCP1403
15 V/50 mA PFM Step-Up
DC-DC Converter
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.
