MP3304
DESCRIPTION
The MP3304 is a monolithic step-up converter
designed for driving arrays of WLEDs from 5V
input or a single cell Lithium Ion battery. The
MP3304 uses current mode, fixed frequency
architecture to regulate the LED current, which is
measured through an external current sense
resistor. Its low 200mV feedback voltage reduces
power loss and improves efficiency.
The MP3304 features up to 50kHz true PWM
dimming, which allows the flexible control of the
backlighting luminance under wide range of the
ambient brightness, and also avoids the
possibility of PWM dimming audible noise.
The MP3304 is turned off if an over-voltage
condition is present due to an open circuit
condition. MP3304 also includes under-voltage
lockout, current limiting and thermal overload
protection preventing damage in the event of an
output overload.
The MP3304 is available in small 8-pin QFN
2x3mm package.
