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 A typical. This device is available in a space saving
compact Micro8 package.
