The LT3763 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. Input and output current sensing provides input current limiting and an accurate measurement of these currents. The FBIN pin is provided for applications requiring a peak power tracking function.
Additional features include an accurate external reference voltage for use with the CTRL pins, an accurate UVLO/EN pin that allows for programmable UVLO hysteresis, a PWM driver for LED applications, output voltage fault detection, and thermal shutdown.
