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 pull-up 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.
