Hello. I need to regulate the voltage (22V - 30V) and step it down to 20-22V. I am not able to use LDO voltage regulators due to the fact that they have high forward voltage drop and at arround 22V input I may not be able to get 20V output.
An interestng option I have found is this voltage regulator chip: http://www.ti.com/lit/ds/symlink/tps7a47.pdf
Considering that my input voltage should never be below 22V, I should be able to achieve 20.5V output considering its low forward voltage drop.
Have you got any other suggestions how to achieve 20-22V output from 22-30V input whilst keeping it as simple as possible?
