6-24V to 5V 16A DC-DC Buck Converter Step Down

The DC-DC Step Down Buck Converter is a highly efficient voltage converter that reliably reduces a wide input voltage range from 6 to 24 V to a stable 5 V while providing output currents of up to 16 A. With a conversion efficiency of over 90 percent at 12 V input voltage and a load of 1 to 16 A, energy losses are effectively minimized, ensuring efficient and reliable operation. The particularly low output ripple of under 20 mV makes the converter ideal for sensitive electronic devices and precision applications. Integrated protection features such as over-temperature protection up to 125 °C and output short circuit protection protect both the module and connected consumers from damage. A thermal pad on the back allows for improved heat dissipation when soldered on a larger copper surface, ensuring stable operation even under prolonged high current load. The module has three control pins for flexible integration into control systems. The EN pin allows targeted activation or deactivation of the output via microcontroller, AGND serves as a ground connection, and the PGOOD pin signals the status of the output voltage during normal or faulty operation. The quiescent current is below 2 mA with the output activated and drops to below 3 µA with the output deactivated. Thanks to its compact design, the voltage converter is ideal for robotics, drones, LED lighting, and prototyping.
