Pololu 5V, 2.5A Step-Down Spannungsregler D24V25F5

Artikelnummer: PO2850

Hersteller Artikel Nr.: 2850

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38V and efficiently reduces it to 5V. The board measures only 0.7"x0.7", but it allows a typical continuous output current of up to 2.5A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps.

Überblick

The D24V25Fx family of step-down voltage regulators generates lower output voltages from input voltages as high as 38 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) with typical efficiencies between 85% and 95%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. The available output current is a function of the input voltage and efficiency (see the Typical efficiency and output currentsection below), but the output current can typically be as high as 2.5 A.

At light loads, the switching frequency automatically changes to maintain high efficiencies. These regulators have 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 different voltage versions of this regulator all look very similar, so you should consider adding your own distinguishing marks or labels if you will be working simultaneously with multiple versions. This product page applies to all versions of the D24V25Fx family.

For newer, lower-priced step-down regulators with a similar input voltage range, output current, and size, consider the D24V22Fx family of regulators. Please note that while these D24V22Fx regulators look very similar to the D24V25Fx family of regulators, they do not have the same pinout and are based on a different internal design, so there are fundamental differences in operation. The D24V22Fx family also includes a 12 V option while the D24V25Fx family does not.

For higher-power applications, we carry a slightly larger, pin-compatible, 5 V version of this regulator that has a typical maximum output current of 5 A.

Two even larger, higher-power, 5 V versions of this regulator are also available: one with a typical maximum output current of 6 A, and the other with a typical maximum output current of 9 A. The higher-power versions also have a few additional features, like a ?power good? signal and the ability to lower their output voltage, and they include optional terminal blocks for easy removable connections.

Eigenschaften

  • Input voltage:
    • 4.5 V to 38 V for the version that outputs 3.3 V
    • [output voltage + dropout voltage] to 38 V for output voltages of 5 V and higher (see below for more information on dropout voltage)
  • Fixed 3.3 V, 5 V, 6 V, 7.5 V, or 9 V output (depending on regulator version) with 4% accuracy
  • Typical maximum continuous output current: 2.5 A
  • Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and soft-start
  • Typical efficiency of 85% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
  • Typical no-load quiescent current under 1 mA; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
  • Compact size: 0.7" × 0.7" × 0.35" (17.8 mm × 17.8 mm × 9 mm)
  • Two 0.086? mounting holes for #2 or M2 screws
