How to design a transition mode PFC pre-regulator using the L6564

Introduction
The transition mode (TM) technique is widely used for power factor correction in low and
medium power applications, such as lamp ballasts, high-end adapters, flatscreen TVs,
monitors and PC power supplies, and all switched-mode power supplies that must meet
harmonics reduction regulations.
The L6564 is the latest proposal from STMicroelectronics for these types of applications,
which may require a low-cost power factor correction solution.
The L6
