popularity in the form of the world’s first current-mode control (CMC) chip, the Flyback controller UC1842 from Unitrode. In CMC, there is in effect a (fast-acting) “inner” current loop along with the “outer” (slower) “voltage loop” which carries out the output regulation. See the note on ramp generation
