• 800mA Output Current on Each Channel • 2.5V to 5.5V Input Voltage Range • 1.3MHz Constant Frequency Operation • Low Dropout Operation at 100% Duty Cycle • Synchronous Topology • 0.6V Low Reference Voltage • Typical 0.1 µA Shutdown Current • Current Mode Operation • Over-Temperature Protection • Over-Current Protection • Up to 94% Efficiency • Internally Compensated • Lead Free and Green Devices Available (RoHS Compliant) Applications • TV Tuner/Box • Portable Instrument The APW7139 consists of two independent 1.3MHz 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 APW7139 is ideal for powering portable equipment that runs from a single cell LithiumIon (Li+) battery.
