UCC28950 Basics: Current Sensing, High Primary Currents

Other Parts Discussed in Thread: UCC28950

In applications where large primary currents are expected, around 60Arms {maximum} let's say, other than meeting the input requirements of the CS pin and designing an input stage that can, both, handle these large currents and minimize conduction losses, what other challenges can be expected when utilizing the UCC28950?

Regards,

MM

    Matthew,

    I expect that the challenges will depend on your experience. Getting the timing right between teh sync rectifiers and the primary side swiches has caused some designers problems but read the application notes and the application portionof the data sheet should solve most.
