UCC29900 描述

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. Isolation stage efficiencies of >96% have been demonstrated in reference designs.

ICC controllers operate the switching power stage in high efficiency burst mode at all load levels, rather than the more conventional PWM mode.

The UCC29900 is a highly integrated ICC controller, incorporating all the features necessary to implement a wide range of high efficiency designs.
