I am building a 0-15V 7A power supply with current limiting.
The plan is to use a buck controller and some to3 transistors to take the voltage from 18V to circa 1V above the output voltage. Then use linear regulation to get rid of ripple.
My question is: to do the linear regulation, can I connect an adjustable linear voltage regulator to the base of a power resistor, or is it there a better way? Perhaps taking all the current through the regulator?
Thanks.M
