EVAL6599-200W: 200W, 24V, 12V, 5V, & 3.3V w/PFC

Summary

This note describes the performances of a 200 W reference board, with wide-range mains operation and power-factor-correction (PFC). Its electrical specification is tailored to a typical high-end application for LCD TV or monitor applications.

The main features of this design are the very low no-load input consumption (<0.5 W) and the very high global efficiency, better than 87% at full load and nominal mains voltage (115 - 230 Vac).

The circuit consists of three main blocks; the first is a front-end PFC pre-regulator based on the L6563 PFC controller. The second stage is a multi-resonant half-bridge converter whose control is implemented through the STMicroelectronics L6599 resonant controller. A further auxiliary flyback converter based on the VIPer12A-E off-line primary switcher completes the architecture. This third block is mainly intended for microprocessor supply and display power management operations.
