The Pololu D24V150F9 is a high-current synchronous step-down (buck) voltage regulator that converts input voltages up to 40V down to a fixed 9V output. With up to 15 A available output current and typical efficiencies of 80–95%, it's well suited for powering large loads like motors, LED arrays, and high-power electronics.
The regulator features built-in reverse voltage protection and a power-good output that signals when the regulator cannot adequately maintain the output voltage.
Key Features
- 9V Fixed Output – Stable regulated output from higher voltage sources
- 15 A Output Current – High current capability for demanding loads
- Up to 40V Input – Wide input voltage range
- 80–95% Efficiency – Synchronous switching for minimal heat and power waste
- Reverse Voltage Protection – Safeguards against accidental reverse polarity
- Power-Good Output – Indicates when output voltage is within regulation
Specifications
- Output Voltage – 9V (fixed)
- Output Current – Up to ~15 A

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
