Datasheet Summary
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 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.
