Pin Description
PIN | Description of pin function | PIN | Description of pin function |
1 | +Vin | 5 | +Vout |
2 | GND | 6 | ADJ |
3 | REM | 7 | COM |
4 | GND | 8 | -VOUT |
Note:
REM is the control end of the input voltage,High potential has high voltage output,Low potential shuts off high voltage output.
ADJ is the regulating end of the output voltage,The greater the resistance output, the higher the voltage, because one end is connected to the positive output voltage, the regulation must pay attention to safety.
Our company can remove the functions of REM and ADJ as required by customers.
