MP3202
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 104m V 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.
