Product Description

The EV3304DD-00A is an evaluation board for the MP3304CDD, a monolithic step-up converter designed for driving arrays of WLEDs from 5V input or a single cell Lithium Ion battery. The EV board is optimized for the load of 3 white LEDs in series, 10 strings panel.

The MP3304 uses current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 200mV feedback voltage reduces power loss and improves efficiency.

The MP3304 features up to 50kHz true PWM dimming, which allows the flexible control of the backlighting luminance under wide range of the ambient brightness, and also avoids the possibility of PWM dimming audible noise.

The MP3304 is turned off if an over-voltage condition is present due to an open circuit condition. MP3304 also includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.

The MP3304 is available in small 8-pin QFN (2mm x 3mm) package.
