    PWM Driver Output for LED Applications
    Thermally Enhanced 28-Lead FE Package The LT®3763 is a fixed frequency, synchronous, step-down
    DC/DC controller designed to accurately regulate output
    currents up to 20A. The average current mode controller will maintain inductor current regulation over a wide
    output voltage range from 0V to 55V. Output current is
    set by analog voltages on the CTRL pins and an external
    sense resistor. Voltage regulation and overvoltage protection are set with a voltage divider from the output to the
    FB pin. The switching frequency is programmable from
    200kHz to 1MHz through an external resistor on the RT
    pin or with the SYNC pin and an external clock signal. ...
