I am using the LT3845 buck regulator to step down a voltage from 9 to approx 1.2V.Now, I see that the formula for configuring the Vout is as stated below -
This means I cannot go below 1.231 as Vout. Due to this I change my Vout to 1.3V, this makes my Vout equation as R2 = 0.054*R1.Now, R2 is the upper resistor(conected to the inductor of the buck) and R1 is the lower resistor.
Normally, the upper resistor is higher than the lower one. How is this possible or am I missing something in here please ?
