3.3V, 2.5A Step-Down Voltage Regulator D24V25F3

This D24V25F3 synchronous buck voltage regulator takes an input voltage of up to 38 V and efficiently reduces it to 3.3 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.5 A and features reverse voltage protection. Typical efficiencies of 80% to 95% make this regulator well suited for powering moderate loads like sensors or microprocessor. This regulator has a typical quiescent (no load) current draw of less than 1 mA, and the ENABLE pin can be used to put the boards in a low-power state that reduces the quiescent current to approximately 10 µA to 20 µA per volt on VIN.

The modules have 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.

The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.
