DC-DC Multi-output Buck Converter (3.3V/5V/9V/12V)

Multiple-output DC–DC converters are crucial in various applications that need different DC output voltages. This DC-DC step-down power module can convert 7.5V - 30V input to 3.3V, 5V, 9V, or 12V output (default is 5V). You can easily select the output voltage by short-circuiting the corresponding pads on the back. It can handle up to 5A load current with proper heat dissipation and comes with 70°C over-temperature and overload protections. There's also an onboard LED indicator. It glows solid red when the module is working well and turns off when the protection mechanism activates, and the voltage drops to 0.1V automatically. This multi-voltage buck power module is great for power control systems of LEDs, robots, drones, servos, and low-power motors. It converts 7.5V - 30V input to 3.3V/5V/9V/12V output, has good heat dissipation, and offers over-temperature and overload protections. Its input voltage range is 7.5V - 30V (24V below is recommended), and it has low ripple (30mV). The soldering hole pitch is 2.54mm, and its dimension is 2.7cm*2cm. The shipping list includes one DC-DC multi-voltage output buck power module (3.3V/5V/9V/12V).

This DC-DC converter is easy to use. By default, it outputs 5V with the 5V solder pad short-circuited. If you want a different output voltage, like 3.3V, just disconnect the 5V pad and short-circuit the 3.3V pad. Remember, as it's a step-down converter, the input voltage must be higher than the output voltage, and it works best with a voltage difference of 2V or more. To keep it working well, make sure it has proper heat dissipation, especially when it's operating at high load currents. If the LED indicator goes out, it means the protection mechanism has been triggered, and the voltage has dropped to 0.1V. Don't worry, this is a safety feature to protect the module. Check for any overload or over-temperature issues and try to resolve them before using it again.
