Attention :

This is a DC-DC voltage converter module, you must pay attention to:

: 1 The input voltage cannot be greater than the maximum input range

: 2 The output power cannot be greater than the maximum load for a long time

: 3 The input power must be greater than the output power, because the power consumption of the module itself

Q&A:

Q1 : Why is the output voltage lower than the nominal voltage

The maximum output power can reach 8W, but the maximum power will vary under different conditions. Please refer to the table below for details (10-80% of the maximum power is the most reliable):

: Input DC 3-24V, output ±5V

: Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.1-0.8A

: Input DC 3-24V, output ±6V

: Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.1-0.7A

: Input DC 3-24V, output ±9V

: Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.04-0.6A

: Input DC 3-24V, output ±10V

: Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.03-0.55A

: Input DC 3-24V, output ±12V

: Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.03-0.46A

: Input DC 3.3-24V, output ±15V

: Input voltage: 3.3V/3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.03-0.41A

: Input DC 3.7-24V, output ±18V

: Input voltage: 3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.04-0.31A

: Input DC 3.7-24V, output ±24V

: Input voltage: 3.7V/5V/6V/9V/12V/15V/18V

: Maximum output current: 0.03-0.25A

A1: The input power is too low. Test the input voltage with a multimeter, the input voltage is very low at this time

Q2 : Why is it not outputting negative voltage or the output is too low?

A2 : Negative voltage cannot be used alone. When using negative voltage, the same load must be connected to the positive voltage side.
