AiT‘s A7115B: a 1.5A, 2MHz High Efficiency Buck DC-DC Converter for Powering Portable Equipment
The A7115B is a 2MHz high-efficiency, PWM step-down converter with an 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 1.5A load current from a 2.6V to 6V input voltage. The output voltage can be as low as 0.6V.
Its features include less than 1μA shutdown current, small external components such as ceramic input and output capacitors as well as small inductors while providing low output ripples.
Its Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal shutdown protection improves design reliability.
This device is available in SOT-25 and DFN6(2×2) packages.
