1.2A, 1.1MHz Synchronous Boost Converter Evaluation Board
The EV3120EJ-00A is a Boost converter evaluation board for the MP3120EJ, a synchronous, 1.1MHz fixed frequency, current mode step-up converter with output to input disconnect.
It can startup from an input voltage as low as 0.8V and provides inrush current limiting as well as output short circuit protection.
The output voltage also can be regulated when Uin>Uo, and the P-channel MOS is no longer act as a low impedance switch.
The EV3120EJ-00A regulates the output voltage up to 3.3V from single cell AA battery without the uses of an external Schottky diode.
The MP3120EJ is offered in a TSOT23-6 package.
