MP3202
1.3A Fixed Frequency White LED Driver
The Future of Analog IC Technology
DESCRIPTION
The MP3202 is a step-up converter designed for driving up to 39 white LEDs (13 strings of 3 LEDs each) from a 5V system rail. The MP3202 uses a current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The MP3202 includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload. The MP3202 is available in small 6-pin TSOT23 or 8-pin QFN (2mm x 2mm) packages.
