I'm an entry-level engineer, and I have a design question for the forum: I'm designing a multiphase buck DC/DC converter which will convert roughly 65VDC to 52VDC at up to 150A. I'm using 4 phases, so inductors, etc will be designed to about 40A/phase, MOSFETS will be paralleled for less (about 13A)current, but that is unimportant. The crucial point where this design deviates from the common design is that it is essential that we have current control rather than just a current limit. An external analog comparator signal is to dictate the current setpoint. I'm really wanting to use two Linear LTC3860 controllers, but again they only provide a current limit. Another option is to do a custom design using a PIC microcontroller, but I still need help with how to use the current sense circuit to control the PWM to provide current regulation. Anyone have any ideas? I attached a rough schematic of one of the stages, with the current sense signals going off-sheet to my theoretical controller. Thanks for your help!
