Product Description

The EV3412EJ-00A is an evaluation board for the MP3412, a synchronous step-up WLED driver with true output load disconnection function. The EV board is designed for driving one WLED.

The MP3412 can startup from an input voltage as low as 0.8V and provides in-rush current limiting as well as output short circuit protection. The open load protection is also integrated

A switching frequency of 1MHz minimizes overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Current mode PWM control with internal compensation reduces external parts, thereby saving critical board space.

The device also features low shutdown current of under 1µA. The true output disconnect feature allows the output to be completely discharged in shutdown. It also limits the inrush of current during start-up, minimizing surge current seen by the input supply.

The MP3412 is available in 6-pin thin SOT23 package.
