Evaluation KitGET THIS KIT
The EV3310EQ-00A is an evaluation board for the MP3310, a monolithic step-up converter designed for driving arrays of WLEDs from a wide input supply range. The EV board is optimized for the load of 10 white LEDs in series, 4 strings panel.
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. And it also includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.
The MP3310 is available in small 10-pin QFN 3x3mm package.
