UCC29900 Datasheet Integral Cycle Controller

Manufacturer: Texas Instruments

Overview: PRODUCT PREVIEW UCC29900 www.ti.com Integral Cycle Controller Check for Samples: UCC29900 SLUS923B – APRIL 2009 – REVISED JUNE.

General Description

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.
