APW7134QAITUL中文资料今台电子数据手册PDF规格书

General Description

TheAPW7134 contains two independent 1.5MHz constant frequency, current mode, PWM step-down converters. Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The APW7134 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 600mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The APW7134 can also run at 100 duty cycle for low dropout applications.
