MP3310

47V, 1.3A, Step-up

White LED Driver

with True PWM Dimming

DESCRIPTION

FEATURES

•

Internal 0.3Ω Power MOSFET

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.

Wide 4.5V to 25V Operating Input Range

Drives up to 12 Series White LEDs

Up to 93% Efficiency

True PWM Dimming

Adjustable Switching Frequency

Adjustable Open Load Shutdown Voltage

Internal 1.3A Current Limit

UVLO, Thermal Shutdown

Available in 3mmx3mm QFN-10 Package

The MP3310 features true PWM dimming,

which allows the flexible control of the

backlighting luminance under wide range of the

ambient brightness.

APPLICATIONS

•

LCD Panels

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. The MP3310

also includes under-voltage lockout, current

limiting and thermal overload protection

preventing damage in the event of an output

overload.
