300W DC-DC Buck Convertor, 5~40V to 1.2~35V Adjustable Voltage Step Down Power Supply Module for DIY Application

Struggling with mismatched voltage in your DIY electronics project? The amiciKart 300W XL4016 DC-DC Buck Converter gives you precise, adjustable step-down power — from a wide 5–40V input down to a clean 1.2–35V output — all in one compact, ready-to-use module.

Built around the reliable XL4016 IC, this step-down power supply module is engineered for serious makers, hobbyists, and electronics engineers who need stable, high-current power regulation without building a circuit from scratch. The onboard potentiometers let you independently fine-tune output voltage (CV) and current (CC), giving you full control over your power delivery. With a maximum output of 9A continuous current and up to 300W peak power, it handles everything from Arduino and Raspberry Pi power supplies to motor drivers, LED arrays, battery chargers, and industrial automation rigs. The built-in aluminium heatsink manages thermal load during normal operation — and for sustained high-power use above 65°C, simply add an external cooling fan for uninterrupted performance.

The PCB-mounted design makes integration straightforward — screw-terminal inputs and outputs mean no soldering expertise required. Whether you're powering a 3D printer, a custom robotics platform, or a bench power supply build, this module adapts to your voltage requirement every time.

Backed by a 1-year warranty and dedicated Indian customer support via WhatsApp, call, or email, amiciKart ensures you're never left troubleshooting alone. Enjoy free shipping across India, same-day dispatch on orders before 2 PM, and hassle-free 30-day returns — shop with complete confidence.
