MP3310
47V, 1.3A, Step-up White LED Driver
with True PWM Dimming
DESCRIPTION
The MP3310 is a monolithic step-up converter designed for driving arrays of WLEDs from a wide input supply range. The MP3310 uses current mode, fixed frequency architecture to regulate the LED current to user programmed value set by an external current setting resistor. The switching frequency is also programmable with an external resistor.
The MP3310 features true PWM dimming, which allows the flexible control of the backlighting luminance under wide range of the ambient brightness.
The MP3310 is turned off if an over-voltage condition is present due to an open circuit condition. Use one external resistor voltage divider to program OVP threshold.
