Hi team,
I currently use TPS55340 as a Boost in an application where VIN <= 13.3V, VOUT = 13.6V, and IOUT = 800mA. In a new application, VOUT and IOUT remain the same, but VIN may be as high as 13.9V. I'd like to reuse my existing TPS55340 design if possible. What are the drawbacks/consequences of having VIN > VOUT when using TPS55340 in a Boost topology?
I understand the option to pivot to a SEPIC exists, but I would like to understand what to expect with the current design if VIN > VOUT.
Thank you,
Brian Angiel
