Loop Compensation
TPS65251 is a current mode control dc/dc converter. The error amplifier is a transconductance amplifier with a of
130 A/V.
A typical compensation circuit could be type II (Rc and Cc) to have a phase margin between 60 and 90 degrees,
or type III (Rc, Cc and Cff) to improve the converter transient response. CRoll adds a high frequency pole to
attenuate high-frequency noise when needed. . It may also prevent noise coupling from other rails if there is
possibility of cross coupling in between rails when layout is very compact.
