Key Features:
- Fixed 5 V output with 4% accuracy
- Typical maximum continuous output current: 2.5 A
- Integrated reverse-voltage protection, over-current and short-circuit protection, over-temperature shutoff, and soft-start
- Typical efficiency of 85% to 95%, depending on input voltage and load
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps. It has built-in reverse-voltage protection, short-circuit protection, a thermal shutdown feature that helps prevent damage from overheating, and a soft-start feature that reduces inrush current.
