TPS54531 for VIN = 23.2~25.8V, VOUT = 22V 3.5A Application

Other Parts Discussed in Thread: TPS54531

Hi Team,

my customer is requesting a device for  for VIN = 23.2~25.8V, VOUT = 22V 3.5A application. As they have used TPS54531 before, so I try to generate the design based on TPS54531 as TPS54531 datasheet also indicate it would support near 100% duty cycle for low drop out application. But the WEBENCH can generate the design. would you please suggest if TPS54531 would support this application? if not, why? And would you please suggest any other device for this applicaiton if TPS54531 can't support? thansk.
