LINEAR TECHNOLOGY LT3741IFE-1#PBF DC-DC Controller, Constant Current, 6V to 36V, 1 Output, Synchronous Buck, 1MHz, TSSOP-20

The is a fixed frequency synchronous step-down DC/DC Controller designed to accurately regulate the output current at up to 20A. The average current-mode controller will maintain inductor current regulation over a wide output voltage range of 0V to VIN - 2V. The regulated current is set by an analog voltage on the CTRL pins and an external sense resistor. Due to its unique topology, the LT3741 is capable of sourcing and sinking current. If sinking current is not required, or for parallel applications, use the LT3741-1. The regulated voltage and overvoltage protection are set with a voltage divider from the output to the FB pin. Soft-Start is provided to allow a gradual increase in the regulated current during startup. The switching frequency is programmable from 200 to 1MHz through an external resistor on the RT pin or through the use of the SYNC pin and an external clock signal.
