Pololu 12V, 600mA Step-Down Voltage Regulator D24V6F12

The compact (0.4? × 0.5?) D24V6F12 switching step-down (or buck) voltage regulator takes an input voltage between 15 V and 42 V and efficiently reduces it to 12 V while allowing for a maximum output current of 600 mA. The pins have a 0.1? spacing, making this board compatible with standard solderless breadboards and perfboards.
