A high-efficiency DC-DC step-down (buck) converter that accepts 6–24 V input and delivers a stable 5 V output at up to 16 A. With over 90% conversion efficiency at typical loads and output ripple below 20 mV, it provides clean, reliable power for demanding applications.
The module includes over-temperature protection (125 °C), output short-circuit protection, and a thermal pad on the back for soldering to a large copper area to improve heat dissipation during sustained high-current operation.
Key Features
- Wide Input Range – 6–24 V DC input, stable 5 V ±1% output
- 16 A Maximum Output – Plenty of current for motors, servos, and LEDs
- High Efficiency – Over 90% at 12 V input with 1–16 A load
- Low Ripple – Less than 20 mV output noise
- Built-In Protections – Over-temperature (125 °C) and short-circuit protection
- Thermal Pad – Solder to copper pour for enhanced heat dissipation
- Control Pins – EN (enable/disable), AGND (control ground), and PGOOD (power-good status)
Control Pins
- EN – Enable/disable output via microcontroller IO pin (use a 1 kΩ series resistor)
- AGND – Single ground point for microcontroller control
- PGOOD – Outputs 5 V when output is normal, 0 V during fault or short circuit

Jargon buster
Plain-language definitions for the technical terms used above.
- Buck converter
- A power circuit that reduces a higher DC voltage to a lower DC voltage. It is useful when your supply voltage is too high for a module or microcontroller and you want less heat and better efficiency than a simple linear regulator.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- ESC
- An ESC, or electronic speed controller, is a driver commonly used to control brushless motors, especially in drones and RC vehicles. Compared with a field-oriented control driver, a conventional ESC typically offers less smooth low-speed control and less precise torque or position control.
- 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.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
