LOOP COMPENSATION
The SP6126 includes Type-II internal compensation components for loop
compensation. External compensation components are not required for systems with
tantalum or aluminum electrolytic output capacitors with sufficiently high ESR. Use the
condition below as a guideline to determine whether or not the internal compensation is
sufficient for your design.
Type-II internal compensation is sufficient if the following condition is met:

Creating a Type-III compensation Network
The above condition requires the ESR zero to be at a lower frequency than the double-
pole from the LC filter. If this condition is not met, Type-III compensation should be
used and can be accomplished by placing a series RC combination in parallel with R1
as shown below. The value of CZ can be calculated as follows and RZ selected from
table 1.
