APW7077 Overview
The APW7077/A series are multi- function PWM step-up DC-DC converter with an adaptive voltage mode controller and higher efficiency application from one to four cells battery packs. The APW7077/A series are set PWM operating mode, voltage-mode to follow portable application. And built-in driver pin, EXT pin, for connecting to an external transistor or MOSFET during light load, the device will automatically skip...
