Demonstration Board based on L6599
This is a 200W SMPSU reference design board, with wide-range mains operation and power-factor correction (PFC). Its electrical specification is tailored to a typical high-end application such as an LCD TV or PC monitor. The main features of this design are the very low no-load input consumption (<0.5W) and the very high global efficiency, better than 87% at full load and nominal mains voltage (115 to 230Vac). 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 an 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.
