The UCC3580 family of PWM controllers is designed to implement a variety
of active clamp/reset and synchronous rectifier switching converter topologies. While containing all the necessary functions for fixed frequency, high
performance pulse width modulation, the additional feature of this design is
the inclusion of an auxiliary switch driver which complements the main …
