DFR1015

DFR1015 is a DC-DC multi-output buck converter module (3.3V/5V/9V/12V). 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 and has 70°C 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.

• Low ripple is 30mV
• Soldering hole pitch is 2.54mm (can solder pin headers)
• Dimension is 2.7cmx 2cm(length x width)/1.06 x0.79"

附註

Multiple-output DC–DC converters are essential in a multitude of applications where different DC output voltages are required. 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.
