NCP1417
200 mA DCâDC Stepâup
Converter with Dual Low
Battery Protection
NCP1417 is a monolithic micropower high frequency Boost
(stepâup) voltage switching converter IC specially designed for
battery operated handâheld electronic products up to 200 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 use of a low profile inductor and output
capacitor. Dual LowâBattery Detectors and CycleâbyâCycle Current
Limit provide valueâadded features for various batteryâoperated
applications. With all these functions ON, the quiescent supply current
is only 9.0 mA typical. This device is available in a space saving
compact Micro8t package.
