Figure 9- RZ and CZ in conjunction with internal
compensation components form a Type-III compensation
Loop Compensation for the SP6127EB
L = 3.3uH, C = 22uF/5mOhm ceramic capacitor
From equation (2) f
ESRZERO
= 1.45MHz. From equation (3) f
DBPOLE
= 18.7 kHz. Since the
condition specified in (1) is not met, Type-III compensation has to be used by adding
external components RZ and CZ. Using equation (4) CZ is calculated 34pF (use 33pF).
Following the guideline given in table 1, a 2kOhm RZ was used.
