Figure 1. Example of a variable output buck regulator
There are numerous reasons for creating a variable output buck regulator, such as to control speed of a DC fan, set the voltage for a 4 – 20mA current loop, track another voltage, or for dynamic voltage scaling. The processes for choosing the correct components and verifying the design are examined here.
