General Description
The APW7176A consists of two independent 1.5MHz constant frequency, current mode, and PWM step-down converters. Each converter integrates a main switch with a synchronous rectifier for high efficiency without an ex ternal Schottky diode. The APW7176A is ideal for power ing portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 1A of load current from a 2.7V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The APW7176A can also run at 100% duty cycle for low dropout applications.
