Pololu Step-Down Spannungsregler D24V3ALV

Artikelnummer: PO2101

EAN: 4060137016264

Hersteller-Artikelnr.: 2101

The compact (0.4"x0.6") D24V3ALV switching step-down (or buck) voltage regulator takes an input voltage between 4.5V and 42V and efficiently reduces it to a lower, user-adjustable voltage. It has a output voltage range of 2.5V to 7.5V and a maximum output current of 300mA. The pins have a 0.1"spacing, making this board compatible with standard solderless breadboards and perfboards.

Overview

These adjustable buck (step-down) voltage regulators generate lower, user-adjustable output voltages from a wide input voltage range of 4.5 to 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency of 80%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. The output voltage is set using the board?s trimmer potentiometer, with the two D24VxALV versions having an available range of approximately 2.5 V to 7.5 V and the two D24VxAHVmodels having an available range of approximately 4 V to 25 V. Versions with 300 mA and 600 mA maximum output currents are available.

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

Features

  • input voltage: 4.5 V to 42 V (note: the input voltage should be at least a few volts above the output voltage) 8
  • output adjustable from 2.5 V to 7.5 V (D24VxALV) or 4 V to 25 V (D24VxAHV) 9
  • maximum output current of 300 mA (D24V3Axx) or 600 mA (D24V6Axx) 10
  • 1.25 MHz switching frequency 11
  • 2 mA typical no-load quiescent current (20 µA typical quiescent current with SHDN = 0V) 12
  • integrated over-temperature and over-current shutoff 13
  • small size: 0.6" × 0.4" × 0.16" (15 × 10 × 4 mm) 14
  • weight without header pins: 0.03 oz (0.8 g) 15
