Application Notes
- Understanding and Designing an Active Clamp Current Mode Controlled ConverterPDF, 845 Kb, File published: May 6, 2010
The UCC2897A Current Mode Active Clamp PWM Controller offers a highly integrated feature set resulting in precision control required for an active clamp forward or flyback converter. The UCC2897A data sheet contains all the design details necessary for accurately programming the device. However, there are significant design considerations and trade-offs unique to the active clamp power stage that - Method of Providing Hiccup Operation for UCC2897AEVMPDF, 361 Kb, File published: Aug 27, 2009
This application note is to provide users of the UCC2897AEVM with a method of generating acyclic restart or restart attempt of the EVM should the converter encounter an overcurrent condition including an output short.
