Buck Converter DC 3.3V 9V 12V Selectable Output

Multiple-output DC-DC converters play a crucial role in various applications requiring different DC output voltages. This DC-DC step-down voltage power module efficiently converts an input voltage of 7.5V to 30V into selectable output voltages of 3.3V, 5V, 9V, or 12V (default: 5V). The desired output voltage can be set by short-circuiting the corresponding soldering pads on the back of the module.

Designed for high performance, this module supports up to 5A load current with appropriate heat dissipation. It incorporates safety mechanisms such as a 70°C over-temperature and overload protection system. Additionally, an onboard LED indicator provides real-time status updates, displaying a solid red light during normal operation and turning off when the protection mechanism is triggered, reducing the output voltage to 0.1V.

This versatile multi-voltage buck power module is ideal for use in power control systems, LED applications, robotics, drones, servos, and low-power motors.
 

Key Features

• Converts 7.5V~30V input to an output of 3.3V/5V/9V/12V
• With suitable heat dissipation
• With 70℃ over-temperature and overload protections

Technical Specifications

Instructions for Use

• The module outputs 5V by default, with the corresponding 5V solder pad short-circuited.
• To change the output voltage (e.g., to 3.3V), disconnect the 5V pad and short-circuit the 3.3V solder pad instead.
• Important: As this is a step-down converter, ensure that the input voltage is always higher than the desired output. A voltage difference of at least 2V is recommended for optimal performance.
• The output parameters provided are measured at 25°C, and proper heat dissipation (e.g., heat sinks) is required for continuous high-current loads.

Applications

• Power control systems
• Robotics and drones
• LED lighting systems
• Servo motors and low-power motors
