3)Patterning of the PCB
■
Input and output pattern should be the same width and length.
■
Voltage drop from the output terminal to remote sensing point must be less than 0.2V.
■
ESR from the slave of the output terminal to remote sensing point must be 10mΩ or less
■
Parallel operation should be separated Vin line of each BRxS(Fig 10.2.2)
■
The beat noise reduction of parallel operation, it is effective to put the input CH(Fig 10.2.3)
