Description
Specifications

Multiple-output DC-DC converters are essential in a multitude of applications where different DC output voltages are required. This DC-DC step-down voltage power module converts 7.5V~30V input to an output of 3.3V/5V/9V/12V (default to 5V), which can be selected by short-circuiting the corresponding pads on the back.

It withstands up to 5A load current with suitable heat dissipation (not included) and has 70℃ over-temperature and overload protections. Besides, there is an onboard LED indicator that shows a solid red light when everything works fine and goes out when the protection mechanism is triggered and the voltage automatically drops to 0.1V. The multi-voltage buck power module can be used in power control systems for LEDs, robots, drones, servos, low-power motors, and so on.

This module outputs 5V by default and the corresponding 5V solder pad is short-circuited. To output other voltages, for instance, 3.3V, please disconnect the 5V pad and short-circuit the 3.3V solder pad.

Since this is a step-down converter, the input voltage should be larger than the output, and it works better with a voltage difference of 2V and above.

Note: The output parameters are measured at 25 ℃, and the heat dissipation (heat sinks) is required for continuous large current load.
