Other Parts Discussed in Thread: TPS54202EVM-716, TPS54202
When I look for a DC/DC step down converter solution, I wonder what is the limit input working voltage for a given output voltage.
For exemple, I find interesting the TPS54202, in the datasheet, I can see 4.5V to 28V input voltage, but when I look at the EVM (TPS54202EVM-716), we find 8V-28V input voltage for 5V output voltage.
In DC/DC buck datasheet, it is not clear in general what is the limit input voltage for a given output voltage (something like the "dropout voltage" in LDO).
Some suggestions ?
