產品總覽

The LT3741EFE#PBF 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. 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.
  • Control pin provides accurate control of regulated output current
  • ±1.5% Voltage regulation accuracy
  • ±6% Current regulation accuracy
  • Average current mode control
  • <1µA shutdown current
  • Up to 94% efficiency
  • Additional pin for thermal control of load current
