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