DESCRIPTION

The EV3302-J-01A is an evaluation board for

the MP3302, a step-up converter designed for

driving up to 27 white LEDs from a single cell

lithium Ion battery. The EV board parameters

are optimized for the load of 3 white LEDs in

series, 9 strings paralleled.

The

MP3302

uses

current

mode,

fixed

frequency architecture to regulate the LED

current, which is measured through an external

current sense resistor. Its low 195mV feedback

voltage reduces power loss and improves

efficiency. The MP3302 monitors the output

voltage and turns off the converter if an over-

voltage condition occurs 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 5-pin TSOT23

package.
