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
