Pololu 3.3V, 500mA Step-Down Spannungsregler D24V5F3

Artikelnummer: PO2842

EAN: 4060137016042

Hersteller-Artikelnr.: 2842

The compact (0.4" × 0.5") D24V5F3 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 80% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 3.3 V. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards.

Überblick

The D24V5Fx family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 36 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 93%, which is much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. These regulators have a power-save mode that activates at light loads and a low quiescent (no load) current draw, which make them well suited for low-power applications that are run from a battery.

The different versions of this regulator all look very similar, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels. This product page applies to all eight versions of the D24V5Fx family.

The regulators feature short-circuit/over-current protection, and thermal shutdown helps prevent damage from overheating. The boards do not have reverse-voltage protection.

The picture on the right shows a 1 A D24V10Fx regulator next to a 0.5 A D24V5Fx regulator and a common 7805 linear regulator in a TO-220 package.

Eigenschaften

  • Input voltage:
    • 3 V to 36 V for output voltages of 1.8 V and 2.5 V
    • [output voltage + dropout voltage] to 36 V for output voltages of 3.3 V and higher (see below for more information on dropout voltage)
  • Fixed 1.8 V, 2.5 V, 3.3 V, 5 V, 6 V, 9 V, 12 V, or 15 V output (depending on regulator version) with 4% accuracy
  • Maximum output current: 500 mA
  • Typical efficiency of 80% to 93%
  • 500 kHz switching frequency (when not in power-save mode)
  • 200 µA typical no-load quiescent current
  • Integrated over-temperature and over-current shutoff
  • Small size: 0.5" × 0.4" × 0.1" (13 mm × 10 mm × 3 mm)
