Pololu 9V, 2.3A Step-Down Spannungsregler D24V22F9

Artikelnummer: PO2861

Hersteller Artikel Nr.: 2861

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36V and efficiently reduces it to 9V. The board measures only 0.7"x0.7" yet delivers a typical continuous output current of up to 2.3A and features reverse voltage protection. Typical efficiencies of 90% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. An optional shutdown pin enables a low-power state with a current draw of around 40 µA to 350 µA, depending on the input voltage, and a power-good output indicates when the regulator cannot adequately maintain the output voltage.

Überblick

The D24V22Fx family of step-down voltage regulators generates lower output voltages from input voltages as high as 36 V. They are synchronous switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) with typical efficiencies of 85% to 95%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. These regulators can typically support continuous output currents of over 2 A, though the actual available output current is a function of the input voltage and efficiency (see the Typical efficiency and output current section below). In general, the available output current is a little higher for the lower-voltage versions than it is for the higher-voltage versions, and it decreases as the input voltage increases.

These regulators have a typical quiescent (no load) current draw of around 1 mA, and an enable pin can be used to put the boards in a low-power state that reduces the quiescent current to approximately 5 µA to 10 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 D24V22Fx family.

The D24V22Fx family is intended to replace our older D24V25Fx family of step-down voltage regulators. The two designs have the same size and similar current capabilities and input voltage ranges, but they do not have the same pinout and are based on different internal circuits, so there are fundamental differences in operation. In particular, these newer D24V22Fx regulators have much lower dropout voltages and provide a "power good" signal, and the newer design allows for higher output voltages (e.g. 12 V).

Eigenschaften

  • Input voltage:
    • 4 V to 36 V for the version that outputs 3.3 V
    • [output voltage + dropout voltage] to 36 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, 9 V, or 12 V output (depending on regulator version) with 4% accuracy
  • Typical maximum continuous output current: >2 A
  • Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load
  • Switching frequency: ~400 kHz
  • Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and soft-start
  • 1 mA typical no-load quiescent current; this can be reduced to approximately 5 µA to 10 µA per volt on VIN by disabling the board
  • "Power good" output indicates when the regulator cannot adequately maintain the output voltage
  • Compact size: 0.7" × 0.7" × 0.31" (17.8 mm × 17.8 mm × 8 mm)
  • Two 0.086" mounting holes for #2 or M2 screws
