6-36V to 5V/3.3V 4A DC-DC Buck Converter Step Down

This compact DC-DC Buck module is a powerful solution for voltage conversion. It allows you to step down input voltages of 5-36V to stable 5V or 3.3V with a maximum output current of 4A. The standard output is 5V but can be changed to 3.3V by adjusting a resistor. With its high efficiency of up to 90% and a switching frequency of 500 kHz, the module is ideal for applications requiring reliable power supply. The high-quality immersion gold plating ensures improved durability and reliability. Thanks to its compact design, it can be easily integrated into various projects, particularly for embedded systems and IoT devices.

Features:

• Wide input voltage range: Supports 5-36V input voltage, depending on the output mode.
• Switchable output voltage: Choose between 5V (standard) or 3.3V by soldering a resistor.
• High output current: Provides up to 4A, even 5A with adequate cooling if needed.
• High efficiency: Achieves an energy conversion efficiency of up to 90%.
• Compact design: Easy to integrate into projects with a size of only 33 × 16 × 5.7 mm.
• High-quality workmanship: Immersion gold process for enhanced corrosion resistance and durability.

Application examples:

• Voltage regulation for IoT devices.
• Power supply for microcontrollers and embedded systems.
• Integration into battery-powered devices.
• Use in drones and robotics projects.
