DESCRIPTION

The EV3302DG-00A is an evaluation board for the

MP3302DG, a step-up converter designed for

driving up to 27 white LEDs from a single cell lithium

Ion battery. The EV board is optimized for the load

of 3 white LEDs in series, 9 strings panel.

The MP3302 uses current mode, fixed frequency

architecture to regulate the LED current, which is

measured through an external current sense

resistor. Its low 208mV feedback voltage reduces

power loss and improves efficiency. The MP3302

monitors the output voltage and turns off the

converter if an over-voltage condition is present

due to an open circuit condition.

The MP3302 includes under-voltage lockout,

current limiting and thermal overload protection

preventing damage in the event of an output

overload.

The MP3302 is available in small 8-pin QFN

(2mm x 3mm) package.
