NCP1411
Sync−Rect PFM Step−Up
DC−DC Converter with
Low−Battery Detector and
Ring−Killer
(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. The innovative Ring−Killer
circuitry guarantees quiet operation in discontinuous conduction
mode. With all these functions ON, the device quiescent supply
current is only 9.0 mA typical. This device is available in the space
saving compact Micro8t package.
