NCP1403: Boost Converter, PFM, DC-DC, 15 V, 50 mA
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 included to extend battery operating life. The device can also be configured in step-down and voltage-inverting configurations. This device is available in space-saving TSOP-5package.
