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.
