These high-current step-down (buck) regulators generate a fixed 5 V output from input voltages up to 38 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage and efficiency, but the output current can typically be as high as 9 A.
 
Features:
  • Input voltage: 5 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); this can be lowered by adding an external resistor between FB and VOUT
  • Typical maximum continuous output current between 4 A and 8 A
  • Integrated reverse-voltage protection, over-current and short-circuit protection, over-temperature shutoff, soft-start, and under-voltage lockout
  • Typical efficiency of 80% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
  • 800 μA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
  • “Power good” output indicates when the regulator cannot maintain its set output voltage
  • Compact size: 1.6″ × 0.8″ × 0.3″ (40.6 × 20.3 × 7.6 mm)
  • Four 0.086″ mounting holes for #2 or M2 screws
  • Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board
Specifications:
  • Minimum operating voltage: 5 V
  • Maximum operating voltage: 38 V
  • Continuous output current: 9 A
  • Output voltage: 5 V
  • Reverse voltage protection?: Y
  • Maximum quiescent current: 15 mA
