Pololu Step-Down Spannungsregler D15V70F5S3

Artikelnummer: PO2111

Hersteller Artikel Nr.: 2111

The compact (1.9"×0.6") D15V70F5S3 switching step-down (or buck) voltage regulator takes an input voltage between 4.5 V and 24 V and efficiently reduces it to a lower, user-selectable voltage. The selectable output voltages are 5 V and 3.3 V, and it can deliver 7 A continuous in typical applications.

Beschreibung

Überblick

These buck (step-down) voltage regulators generate lower, user-selectable output voltages from an input voltage range of 4.5 to 24 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical (when the output current is several amps) efficiency of approximately 90%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. The output voltage defaults to 5 V and can be changed to 3.3 V by jumping 3V3 SELECT.

The regulator has under-voltage and short-circuit protection, and thermal shutdown prevents damage from overheating. The board has reverse-voltage protection.
