NCP1410

250 mA Sync-Rect PFM

Step-Up DC-DC Converter

with Low-Battery Detector

NCP1410 is a monolithic micropower high frequency Boost

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

battery operated hand–held electronic products up to 250 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 low profile inductor and output capacitor being

used. Low–Battery Detector, Logic–Controlled Shutdown and

Cycle–by–Cycle Current Limit provide value–added features for

various battery–operated applications. With all these functions ON,

the device quiescent supply current is only 9.0 µA typical. This device

is available in space saving compact Micro8 package.
