MP3306
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 202m V 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 pletely discharged. The MP3306 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.
