Low power audio power supply
Car audio amplifier dual power board
LCD power supply
Instrumentation equipment
Attention:
This is a DC-DC voltage converter module, must be noted when using:
1. Input voltage can not be greater than the maximum input range
2. Output power can not be greater than the maximum load for a long time
3. Input power must be greater than the output power because of the power consumption of the module itself
Q & A:
Q1: Why output voltage is less than the nominal voltage
A1: Input power supply power is too low. Test the input voltage with a multimeter, at this time of the input voltage is very low
Q2: Why is the negative voltage not output or the output too low?
A2: The negative voltage cannot be used alone. When using a negative voltage, the same load must be connected at the positive voltage terminal.
The maximum output power can reach 8W, but the maximum power will vary under different conditions. For details, please refer to the following table(10-80% of the maximum power is the most reliable):
