SyncRect PFM StepUp
DCDC Converter with
LowBattery Detector and
RingKiller
NCP1411 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. 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 A typical. This device is available in the space
saving compact Micro8 package.
