1. The CTRL pin voltage is referenced to GND.
Note:
Example:
1. Min. load shouldn‘t be less than 5%, otherwise ripple maybe increase
dramatically. Operation under minimum load will not damage the converter,
however, they may not meet all specification listed.

If it is required to further reduce input and output ripple, properly incre-
ase the input & output of additional capacitors Cin and Cout or select
capacitors of low equivalent impedance provided that the capacitance
is no larger than the max. capacitive load of the product.
