Overview

NCP1509 Up to 500 mA, 1 MHz, High Efficiency Synchronous Step−Down DC−DC Converter in DFN Package The NCP1509 step−down PWM DC−DC converter is optimized for portable applications powered from 1−cell Li−ion or 3 cell Alkaline/NiCd/NiMH batteries.

This DC−DC converter utilizes a current−mode control architecture for easy compensation and better line regulation.

It also uses synchronous rectification to increase efficiency and reduce external part count.
