First question asked
When setting the output voltage range of the IRPS5401, the data sheet says the maximum output is 5.1V when using a divider into the FB input pin.
For Vo > 2.55V, a divider is used to set feedback to 1/2 of Vout, so 5.1V would map down to 2.55. Would it be permissible to slightly offset that FB in order to get another 0.2V output?
We need to get 5.3V output from one of the channels.

Thank you, John

Hi,

 

   Thank you for posting on the Infineon community forum. 

As per your request, it is not suggested to vary the feedback resistor to get an additional 0.2V.

The internal IDAC and other components are rated for 5.1V. 
Please use an additional converter on the output side to achieve this requirement.
