Notice:
1 In order to oain a more stable voltage, it is recommended that the output be greater than 10MA
2 V- cannot be used alone, or there is no voltage output. But you can use V+
application:
ADC/DAC/operational amplifier reference voltage
RS232 RS485 RS422 bus
Audio equment
Low power audio power supply
Car audio amplifier dual power supply board
LCD power supply
Instrumentation
Attention:
This is a 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 of the power consumption of the module itself
Q&A:
: Why is the output voltage lower than the nominal voltage
The maximum output power can reach 8W, but the maximum power will be different under different conditions. For details, please refer to the following table (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. Use a multimeter to test the input voltage, the input voltage is very low at this time
Q2: Why does it not output negative voltage or the output is too low?
A2: Negative voltage cannot be used alone. When using a negative voltage, the same load must be connected to the positive voltage terminal.
