Description

Description

This step-down (buck) regulator generates a fixed 5 V output from input voltages up to 38 V. It is a switching regulator and has a typical efficiency between 85% to 95%. The available output current is a function of the input voltage and efficiency, but the input current can typically be as high as 5 A. The regulator has a typical quiescent current draw of less than 1 mA, and the ENABLE pin can be used to put the board in a low-power state that reduces the quiescent current to approximately 10 µA to 20 µA per volt on VIN.


Features

  • Input voltage: 6V to 38V
  • Typical maximum continuous output current: 5 A
  • Typical efficiency of 85% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
  • Compact size: 0.7″ × 0.8″ × 0.35″
  • Fixed 5 V output (with 4% accuracy)
  • Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, soft-start, and under-voltage lockout
  • 700 μA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
