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

Features

  • 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)

Guess I need to jump this

SHDN pin can be directly connected to VIN to permanently enable the board. You should not leave this pin disconnected as this can result in unpredictable behavior.
