Working Principle

The CA-1235 works as a DC-DC buck converter. It receives a higher DC input voltage and reduces it to one of the available lower output voltage settings.

The MP1495 regulator uses synchronous switching technology to regulate the output voltage efficiently.

Connection Information

Input Connections:

• IN+ : Positive DC input

• IN− : Negative DC input

Output Connections:

• OUT+ : Positive regulated output

• OUT− : Negative output

Select the required output voltage using the module's designated voltage-selection points. Verify the selected output with a multimeter before connecting your load.

Important Installation Precautions

• Use a DC input supply within the specified 5V–15V range.

• Observe correct input polarity.

• Select the required output voltage before connecting your device.

• Never exceed the maximum output current rating.

• Provide adequate ventilation and cooling under higher loads.

• Do not connect an output load before checking the output voltage.

• This is a step-down converter and cannot increase the input voltage.
