DCRIPTION
The MP3302 is a step-up converter digned for driving arrays of WLEDS from a single cell Lithium Ion battery. The MP3302 us current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense ristor. Its low 200mV feedback voltage reduc power loss and improv efficiency. The MP3302 is turned off if an over-voltage condition is prent due to an open circuit condition. The MP3302 includ under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload. The MP3302 is available in all 5-pin TSOT23 and 8-pin QFN (2mm x 3mm) packag.
