Solution for designing a transition mode
PFC preregulator with the L6562A

Introduction
The TM (transition mode) technique is widely used for power factor correction in low and
middle power applications, such as lamp ballasts, high-end adapters, flat TVs and monitors,
and PC power supplies. The L6562A is the latest proposal from STMicroelectronics for this
market as well as emerging markets that may require a low-cost power factor correction.
Based on a well-establis
