NCP1417

200 mA DC-DC Step-up

Converter with Dual Low

Battery Protection

NCP1417 is a monolithic micropower high frequency Boost

(step–up) voltage switching converter IC specially designed for

battery operated hand–held electronic products up to 200 mA loading.

It integrates Synchronous Rectifier for improving efficiency as well as

eliminating the external Schottky Diode. High switching frequency

(up to 600 kHz) allows use of a low profile inductor and output

capacitor. Dual Low–Battery Detectors and Cycle–by–Cycle Current

Limit provide value–added features for various battery–operated

applications. With all these functions ON, the quiescent supply current

is only 9.0 mA typical. This device is available in a space saving

compact Micro8t package.
