3.4.3.  Reference Design for Power Supply 

The power design for the module is very important, as the performance of the module largely depends on 
the power source. The power supply of SC200L should be able to provide sufficient current up to 3A at 
least. If the voltage drop between the input and output is not too high, it is suggested to use an LDO to 
supply power for the module. If there is a big voltage difference between the input source and the desired 
output (VBAT), a buck converter is recommended. 

 
The following figure shows a reference design for +5V input power source.

NOTES

 

1.  It is suggested that customers should switch off the power supply for the module in an abnormal 

state, and then switch on the power to restart the module. 

2.  The module supports the battery charging function by default. If the above power supply design is 

adopted, please make sure the charging function is disabled by software or connect VBAT to 
Schottky diode in series to avoid the reverse current to the power supply chip.
