TPS552892-Q1: ERROR AMPLIFIER

Part Number: TPS552892-Q1

Dear team:

 Could you kindly help me with a few problems about compensation loop:

1. Isink、source、Vcclph、Vcclpl:What do these parameters mean?Dose these parameters limit loop compensation parameter selection?

2. The Isink tested in Vcomp = 1.5V condition, but Vcclph means Vcomp max 1.2V?

3. Max cut-off frequency usually depend on Fsw & RHPZ,and also need to consider the EA  bandwidth which not mentioned in datasheet,so what is the normal bandwidth of the error amplifier inside the DCDC chip?

thanks a lot!

Best regards,

Qin
