Other Parts Discussed in Thread: UCC28250
Hello.
I'm designing a power supply that need pre-biased start-up functions for parallel operations. PWM controller is UCC28251 placed on the primary side.
SR outputs are overlapping signals at normal conditions, but during soft-start interval they starting with no overlapping (less than 50% duty cycle) with dead-time equal to PS delay.
Is it OK for this controller? Can this issue cause some troubles including power supply damaging during pre-biased start-up?
Thanks for Your answer.
