Hi Experts,
I am planning to use LM358B as voltage follower. However, I have meet one troublesome issue. I have Vin ranging from 5-48V, and then this Vin will go through a resistor divider circuit wit factor 0.6. Then, the Vfb will be ranging from 3-28.8V, and to the LM358B voltage follower. However, I need to get a Vout ranging from 3.2-28V at the LM358B output. The detail design solution showing below. Could you help give some suggestions how to improve the circuit to obtain 3.2-28V output voltage?
Thanks!
Dylan
