APW7176

APW7176 Dual 1.5MHz, 1A Synchronous Step-Down Converter Features 1A Output Current on Each Channel 2.7V to 5.5V Input Voltage Range 1.5MHz Constant Frequency Operation Low Dropout Operation at 100% Duty Cycle Synchronous Topology 0.6V Low Reference Voltage Current Mode Operation Over-Temperature Protection Over-Current Protection Up to 94% Efficiency Internally Compensated Lead Free and Green Devices Available (RoHS Compliant) General Description The APW7176 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 external Schottky diode. The APW7176 is ideal for powering portable equipment that runs from a single cell LithiumIon (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 APW7176 can also run at 100% duty cycle for low dropout applications.
