A7115B DC-DC CONVERTER BUCK(STEP-DOWN) 1.5A 2MHz SYNCHRONOUS
●The A7115B is a 2MHz high-efficiency, PWM step-down converter with integrated main switch and synchronous rectifier that is ideal for powering portable equipment that runs from a single Li-on or Li-Polymer battery.
●The A7115B can supply up to up to 1.5A load current from a 2.6V to 5.5V input voltage. The output voltage can be as low as 0.6V.
●The A7115B features include <1uA shutdown current, small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making A7115B an ideal replacement for large power consuming linear regulators. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal shutdown protection improves design reliability.
●The A7115B is available in SOT-25 and DFN6 (2x2) packages.
