MP3367 & MPQ3367 6-Channel Boost WLED Drivers
Monolithic Power Systems (MPS) MP3367 and MPQ3367 6-Channel Boost WLED Drivers are step-up converters designed to drive white LED arrays as backlighting in small to midsized LCD panels. The MP3367 and MPQ3367 use peak current mode as pulse-width modulation (PWM) control architecture to regulate the boost converter. Six current source channels are applied to the LED cathode to adjust the LED brightness. The MP3367 and MPQ3367 regulate the current in each LED string to the value set by an external current setting resistor, with 2.5% current regulation accuracy between strings.
