200W DC-DC Buck Converter

The 200W DC-DC Buck Converter is a compact, high-efficiency step-down voltage regulator designed for a wide range of electronic, industrial, and DIY applications. Utilizing advanced PWM modulation and the XL4016 switching regulator chip, this converter provides reliable voltage regulation with robust protection features, including over-current, over-temperature, and short-circuit protection.

Supporting an input voltage range of DC 4–40V, the converter delivers an adjustable output voltage from 1.25V to 36V DC, making it suitable for powering various devices and systems. With a maximum output current of 8A and a peak power output of 200W, this module is ideal for high-demand applications. For continuous operation above 5A, it is recommended to use additional fan cooling to maintain optimal performance and prevent overheating.

The 200W DC-DC Buck Converter achieves a high conversion efficiency of up to 94% and operates at a switching frequency of 180kHz, ensuring stable and efficient power delivery. The compact size (61 x 41 x 27mm) allows for easy integration into tight spaces, while the panel mounting option with an extended potentiometer handle provides convenient voltage adjustment and secure installation.

This module is perfect for battery charging, LED drivers, motor control, and other applications requiring precise voltage regulation and high current output. The package includes one DC step-down voltage power module, with two styles shipped randomly.
