Application Notes
- UCC28517 100-W PFC power converter with 12-V, 8-W bias supply, Part 2PDF, 224 Kb, File published: Feb 28, 2005
To conclude the review of the UCC28517 PFC supply, this article covers the design of the second 12-V, 8-W power stage to be used as an auxiliary bias supply. - UCC28517 100-W PFC power converter with 12-V, 8-W bias supply, Part 1PDF, 202 Kb, File published: Feb 28, 2005
Power factor corrected (PFC) preregulators are generally used in ac/dc converters operating above 75 W or to meet line harmonic requirements. This article reviews the design of a 100-W ac/dc power stage with PFC. - Bootstrap Circuit for Green Mode ApplicationsPDF, 111 Kb, File published: Jan 27, 2006

The synchronization of multiple PWM and PFC controllers is desirable for many reasons. The most common reason is that it keeps all the noise at one particular frequency and makes it easier to filter. The circuit described changes the slope of the ramp to lock the converter’s switching frequency to an applied signal by a phase locked loop turning it into a voltage controlled oscillator.
