NCP1404 Overview
NCP1404 Series Product Preview 350 mA PWM/PFM Step-Up DC-DC Converter with Low Battery Detector The NCP1404 series are monolithic PWM/PFM step up DC to DC converters which can automatically change operation mode from PWM to PFM at light loads to improve efficiency at light loads. With only four external ponents, this series allow a simple means to implement highly efficient converters for powering up portable...
