XY-SJVA-4 Adjustable Buck Boost Regulator

The DC-to-DC converter module is an advanced and high-performance automatic power supply solution designed to deliver stable output voltage under fluctuating input conditions. Using an intelligent buck-boost topology, this smart DC power module can automatically step the input voltage up or down, ensuring a constant and adjustable output for connected loads. This makes it an ideal choice for applications where voltage stability is critical.

The XY-SJV-4 adjustable DC-DC regulator automatically detects whether the input voltage is higher or lower than the desired output and seamlessly switches between boost and buck modes without any manual intervention. This precise automatic operation reduces stress on connected devices, extends component lifespan, and protects circuits from damage caused by sudden voltage drops or spikes.

With high efficiency and a safe circuit design, the 0.5V–30V adjustable automatic DC-DC regulator is suitable for continuous and long-term operation. Built-in protection circuits against voltage fluctuations and abnormal operating conditions help safeguard sensitive electronic circuits. The precise adjustable output voltage allows compatibility with a wide range of projects and loads.

This adjustable DC-DC voltage regulator is ideal for professional electronics projects, battery and solar power systems, automotive electronics, microcontroller boards, high-power LEDs, and industrial modules. If you’re looking for a reliable, stable, and versatile solution for intelligent voltage management, this buck-boost converter module is one of the best options available.
