EVAL6599-400W-T: 400W, 200V @ 1.5A, 75V @ 1A, 5V @ 1A, 3.3V @ 700mA

Summary

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 90% 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 with two output voltages of +200 V/300 W and 75 V/75 W, whose control is implemented through the L6599 resonant controller. A further auxiliary flyback converter based on the VIPer12A off-line primary switcher completes the architecture. This third block, delivering a total power of 7 W on two output voltages (+3.3 V and +5 V), is mainly intended for microprocessor supply and display power management operations
