Product Description

The EV28119 evaluation board is designed for low dropout step down converter applications. It implements the MP28119 1.7MHz fixed frequency, current-mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery. It can supply 600mA of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. In 100% Duty Cycle Dropout operation, it works with minimum input voltage as low as output voltage. It can output voltage as low as 1V from 6V input due to its very small minimum on-time. Furthermore, with the output discharge function, even at no load, the output voltage falls quickly when disabled.
