Product Description

The MP2136 is a 2MHz constant frequency, current mode, PWM step-down converter with integrated main switch and synchronous rectifier that is ideal for powering portable equipment that runs from a single Li-Ion or Li-Polymer battery. The MP2136 can supply up to 1A load current from a 2.5V to 6V input voltage. The output voltage can be as low as 0.6V. Additional features include <1? shutdown current, internal soft-start, cycle-by-cycle over current protection, short circuit protection, and thermal shutdown. The MP2136 is available in a 6-pin, QFN6 2?mm package.
