Product Description

What is DC-DC Buck Converter?

The HJ-0890 DC-DC Buck Converter is a high-efficiency step-down DC-DC converter designed to provide stable, reliable power for electronics, smart home devices, and other 3C products. Also referred to as a buck converter module or DC-DC voltage regulator, this device is ideal for battery-powered systems and energy-sensitive applications. OEM customization is available, allowing output voltage and current parameters to be tailored according to your needs.

Certified with CE and ROHS, the HJ-0890 ensures safety and compliance for global applications.

A DC-DC Buck Converter is an electronic device that efficiently lowers (steps down) a higher input voltage to a lower output voltage. Using pulse-width modulation (PWM), it precisely regulates voltage to provide a stable and reliable power supply for various electronic devices.

Key Features

1. Voltage Reduction – Converts a higher DC input voltage (DC08–90V) to a lower, stable output voltage, controlling internal transistors for precise regulation.

2. High Efficiency – Achieves work efficiency ≥80%, minimizing energy loss during voltage conversion.

3. Compact Design – Space-saving layout makes it ideal for applications where efficiency and size matter.

4. Wide Applications – Perfect for 3C products, smart home devices, automotive electronics, and renewable energy systems.

5. Multiple Protection Features – Overvoltage protection, short-circuit protection, overload protection, and temperature protection safeguard both the converter and connected devices.

Advantages

• Energy Efficiency – Minimizes power loss, extends battery life, and reduces heat generation.

• Stable Voltage Regulation – Maintains consistent output voltage even with fluctuating input or varying load conditions.
