Part Number: UCC29002
Hello
I am considering using the UCC29002 load share controller to parallel two buck converters. The controller is accurate enough for my requirements in steady-state, however, I can't find any data in regard to the UCC29002's performance during transient conditions. According to the user guide and the data sheet, the bandwidth of the controller is recommended to be 1/10th of the dc-dc converter's loop bandwidth. Therefore the control loop basically does not respond to high slew rate transients and the current sharing error is proportional to the difference between the output impedances of the two converters. Is this correct?
Does TI offer a more advanced controller that has higher transient response?
Thanks,
Chuck
