Overview

NCP1523 3 MHz, 600 mA, High−Efficiency, Adjustable Output Voltage Step−down Converter The NCP1523 step−down PWM DC−DC converter is optimized for portable applications powered from 1−cell Li−ion or 3 cell Alkaline/NiCd/NiMH batteries.
The device is available in an adjustable output voltage from 0.
9 V to 3.
3 V.
It uses synchronous rectification to increase efficiency and reduce external part count.
The device also has a built−in 3 MHz (nominal) oscillator which reduces component size by allowing use of a small inductor and capacitors.
NCP1523 is available in automatic switching PWM/PFM (NCP1523FCT2G) improving system efficiency and in PWM mode only (NCP1523BFCT2G) offering a very efficient lo...
