Pololu 12V, 1A Step-Down Voltage Regulator D24V10F12

 

The D24V10Fx family of step-down voltage regulators features the Intersil ISL85410 1A synchronous buck regulator and 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) with typical efficiencies between 80% and 95%, 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 applications that are run from a battery. These regulators are available in five different fixed output voltages:


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 five versions of the D24V10Fx family.

The SHDN pin can be used to put the board in a low-power state that reduces the quiescent current to approximately 10 µA to 20 µA per volt on VIN, and a PG (power good) output can be used to monitor the state of the regulator’s output voltage.

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

If you do not need quite as much current, consider the very similar D24V5Fx family of step-down voltage regulators, which can deliver up to 500 mA in a wide range of output voltages:

 

Features

  • Input voltage: [output voltage + dropout voltage] to 36 V (see below for more information on dropout voltage)
  • Fixed 3.3 V, 5 V, 6 V, 9 V, or 12 V output (depending on regulator version) with 4% accuracy
  • Maximum output current: 1 A
  • Typical efficiency of 80% to 93%
  • 500 kHz switching frequency (when not in power-save mode)
  • 2 ms soft-start reduces in-rush current on power-up
  • 200 μA typical no-load quiescent current
  • Over-current and short-circuit protection, over-temperature shutoff
  • Small size: 0.7″ × 0.5″ × 0.14″ (18 mm × 13 mm × 3.5 mm)
