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.
