Pololu 12V, 300mA Step-Down Spannungsregler D24V3F12

Pololu 12V, 300mA Step-Down Spannungsregler D24V3F12

The compact (0.4" × 0.5") D24V3F12 switching step-down (or buck) voltage regulator takes an input voltage between 14.5 V and 42 V and efficiently reduces it to 12 V while allowing for a maximum output current of 300 mA. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards.

Überblick

These buck (step-down) voltage regulators generate lower output voltages from input voltages as high as 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. This regulator is available with a fixed 3.3 V, 5 V, 9 V, or 12 V output, and two versions are available for each voltage, one with a 300 mA maximum output current (D24V3Fx) and one with a 600 mA maximum output current (D24V6Fx):

The regulator has short-circuit protection, and thermal shutdown prevents damage from overheating. The board does not have reverse-voltage protection.
