Dear AD,

I am designing power converter with LT8609A.  I was refering the datasheet document file "LT8609-8609A-8609B.pdf ".  I probably found some errors in the datasheet of the IC. In sheet no. 14 under Applications Information, FB Resistor Network , the formula given for calculating the bottom resistor value in feedback network as below screen sh :

but the formula does not yield the value properly and the calculated value will be wrong.

I reverse calculated the value for bottom resistor and the correct formula , which yeilds the correct value is as below

Please evaluate for any errors and send us the approval for our application
