XL4016 DC-DC step-down converter power supply 1.25-35 V 8 A 200 W - buck

XL4016 DC-DC 200 W step-down voltage converter

An efficient step-down power supply module based on the XL4016 IC. It allows smooth and precise adjustment of the output voltage from 1.25 V to 35 V with an input voltage from 4 V to 38 V. The device offers high efficiency of around ~90% and compact dimensions. It works well as a power supply for Arduino, Raspberry Pi, ESP8266, and ESP32.

Key technical specifications

• Input voltage: 4 - 38 V
• Output voltage: 1.25 - 35 V
• Maximum current: 5 A (up to 8 A with active cooling)
• Maximum power: 200 W
• Efficiency: ~90%
• Dimensions: 61 x 38 x 27 mm

Precise parameter adjustment

The module is fitted with multi-turn potentiometers that allow accurate adjustment of the voltage level to suit the powered circuit. Turning the potentiometer counterclockwise decreases the voltage, while turning it clockwise increases it. This gives full control over the operating parameters.
