Pololu 5V, 5A 天干天干啦夜天干天2017 Voltage Regulator D24V50F5
This small synchronous switching 天干天干啦夜天干天2017 (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″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos. 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.

Notes:
- 1
- Without included optional headers.
- 2
- For small loads; this voltage rises approximately linearly up to around 6.2 V at 5 A output.
- 3
- Typical. Actual continuous output current limited by thermal dissipation.
- 4
- Typical worst case (i.e. with VIN close to 6V). The ENABLE pin can be used to reduce the quiescent current to a few hundred microamps.
