TPS53659: tps53569 How to calculate compensation design inputs

Hello All,

 

I am designing a 0.8V 80 A 4 phase dc-dc converter. I am using the TPS53569 digital pwm controller and the CSD95495 power block.

Can someone point me to a resource that explains how the 3rd generation DCAP+ modulator works and how to determine the modulator gain for DCAP+?

 

Any help would be greatly appreciated,
