This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 7.5 V. The board measures only 17.8 mm x 17.8 mm, 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.

Features

Input voltage:
- 4.5 V to 38 V for the version that outputs 3.3 V
- [output voltage + dropout voltage] to 38 V for output voltages of 5 V and higher (see below for more information on dropout voltage)
Fixed 3.3 V, 5 V, 6 V, 7.5 V, or 9 V output (depending on regulator version) 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; the switching frequency automatically changes at light loads to maintain high efficiencies
Typical no-load quiescent current under 1 mA; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
Compact size: 17.8 mm x 17.8 mm x 9 mm
Weight: 2.6 g (Without included optional headers.)
Two 0.086″ mounting holes for #2 or M2 screws

General specifications

Minimum operating voltage: 8.3 V (For small loads; this voltage rises approximately linearly up to around 8.7 V at 2.5 A output.)
Maximum operating voltage: 38 V
Output voltage: 7.5 V
Reverse voltage protection?: Y
Maximum quiescent current: 1 mA (Typical worst case. The ENABLE pin can be used to reduce the quiescent current to a few hundred microamps.)
