DESCRIPTION

The MP3306 is a step-up converter designed

for driving white LEDs from 3V to 12V power

supply. The MP3306 uses current mode, fixed

frequency architecture to regulate the LED

current, which is measured through an external

high-side current sense resistor. The low

202mV feedback voltage and synchronous

rectification reduces power loss and improves

efficiency.

The MP3306 is turned off if an over-voltage

condition is present due to an open circuit

condition. The output disconnect feature allows

the output to be completely discharged.

TheMP3306 includes under-voltage lockout,

current limiting, output short protection and

thermal overload protection.

The MP3306 is available in small 12-pin QFN

(2mm x 2mm) package.
