This step-down (buck) regulator generates a fixed 5 V output from input voltages up to 38 V. It is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) and has a typical efficiency between 85% to 95%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. The available output current is a function of the input voltage and efficiency, but the output current can typically be as high as 5 A.
 
Features:
  • Input voltage: 6 V to 38 V (see below for more details on the regulator’s dropout voltage, which affects the low end of the operating range)
  • Fixed 5 V output (with 4% accuracy)
  • Typical maximum continuous output current: 5 A
  • Integrated reverse-voltage protection, over-current and short-circuit protection, over-temperature shutoff, soft-start, and under-voltage lockout
  • Typical efficiency of 85% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
  • 700 μA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
  • Compact size: 0.7″ × 0.8″ × 0.35″ (17.8 mm × 20.3 mm × 8.8 mm)
  • Two 0.086″ mounting holes for #2 or M2 screws
Specifications:
  • Minimum operating voltage: 6 V
  • Maximum operating voltage: 38 V
  • Continuous output current: 5 A
  • Output voltage: 5 V
  • Reverse voltage protection?: Y
  • Maximum quiescent current: 0.8 mA
