NCP1423
400 mA SyncRect PFM
StepUp DCDC Converter
with TrueCutoff and
RingKiller
NCP1423 is a monolithic micropower high frequency stepup
switching converter IC specially designed for battery operated
handheld electronic products. 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. When the IC is disabled,
internal conduction path from LX or BAT to OUT is blocked, OUT pin
is isolated from the battery. This achieves TrueCutoff. RingKiller is
also integrated to eliminate the high frequency ringing in discontinuous
conduction mode. LowBattery Detector, CyclebyCycle Current
Limit, Overvoltage Protection and Thermal Shutdown provide
valueadded features for various battery operated application. With all
of these functions ON, the quiescent supply current is only 9.0 A. This
device is available in compact Micro10 package.
