DESCRIPTION
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.
FEATURES
• Wide 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
• Fully Assembled and Tested
APPLICATIONS
• LCD Panels
• Digital Picture Frames
• Handheld Computers and PDAs
• Digital Still Cameras
• Small LCD Displays
