Monolithic Power Systems EV3414-J-00A

Description

The EV3414-J-00A is a Boost converter evaluation board for the MP3414, asynchronous, 1MHz fixed frequency, current mode step-up converter with output to input disconnect. The device can step up single-celland two-cell alkaline, NiCd, and NiMH batteries up to 4V.

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 VIN>VOUT, and the P-channel MOS is no longer act as a low impedance switch.

The EV3414-J-00A regulates the output voltage up to 3.3V from single cell AA battery without the uses of an external Schottky diode.

The MP3414 is offered in a TSOT23-8 package.
