UCC29900 Overview
The UCC29900 is a new class of Integral Cycle Control (ICC) controller designed to implement ultra-high efficiency isolated switching power stages. ICC can be employed to achieve ultra-high conversion efficiency over a wide range of load current. The hysteretic mode output voltage control employed exhibits fast transient response, with almost zero output overshoot.
