PWM Step-Up DC-DC Converter

The APW7077 APW7077A series are multi- function PWM step- up DC-DC Converter with an adaptive voltage mode con- troller and higher efficiency application from one to four cells battery packs. The APW7077 APW7077A series are set PWM operating mode, voltage-mode to follow portable application. And built-in driver pin, EXT pin, for con- necting to an external Transistor or MOSFET during light load, the device will automatically skip switching cycles to maintain high efficiency. The APW7077 APW7077A series consist of PWM Controller reference voltage, phase compensation, Oscillator soft-start, driver block. It will be provided to operate suitable voltage without external compensation circuit. The APW7077 APW7077A se- ries have fixed voltage and adjustable voltage version from a wide input voltage ranges 0.7V to 5.5V for step- up DC-DC Converter The start-up is guaranteed at 1V and the device is operating down to 0.7V, and provid- ing up to 300mA loading current. Besides, low quies- cent current (switch-off) is guaranteed. By Anpec Electronics Corporation
