Product Preview
250 mA Sync-Rect PFM
Step-Up DC-DC Converter
with Low-Battery Detector
NCP1410 is a monolithic micropower high frequency step鈥搖p
voltage switching converter IC specially designed for battery operated
hand鈥揾eld 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鈥揃attery Detector, Logic鈥揅ontrolled Shutdown and
Cycle鈥揵y鈥揅ycle Current Limit provide value鈥揳dded features for
various battery鈥搊perated applications. With all these functions ON,
the quiescent supply current is only 9.0
mA
typical. This device is
available in a compact Micro8 package.
