EVL6564H-100W 100 W transition-mode PFC pre-regulator demonstration board based on the L6564H Data brief Features Line voltage range: 90 to 265 Vac Minimum line frequency (f ): 47 Hz L Regulated output voltage: 400 V Rated output power: 100 W Maximum 2f output voltage ripple: 20 V pk-pk L Hold-up time: 10 ms (V after hold-up time: DROP 300 V) Minimum switching frequency: 40 kHz Minimum estimated efficiency: 92% ( V = in 90 Vac, P = 100 W) OUT EVL6564H-100W Maximum ambient temperature: 50 C isolated DC-DC converter that provides the output PCB type and size: single side, 35 m, CEM-1, rails required by the load. 90 x 83 mm Description This demonstration board is based on the new transition-mode PFC controller L6564H and implements a 100 W, wide-range mains input, PFC pre-conditioner suitable for ballast, adapters, flat screen displays, and all SMPS having to meet IEC61000-3-2 or JEITA-MITI regulations. The L6564H is a current-mode PFC controller operating in transition mode (TM) which embeds the same features existing in the L6564 with the addition of a high voltage startup source. These functions make the IC especially suitable for applications that must be compliant with energy saving regulations and where the PFC pre- regulator works as the master stage. The EVAL6564H-100W implements a power factor correction (PFC) pre-regulator 100 W, continuous power, on a regulated 400 V rail from a wide-range mains voltage and providing for the reduction of the mains harmonics, allowing the European EN61000-3-2 or the Japanese JEITA- MITI standard to be met. The regulated output voltage is typically the input for the cascaded April 2012 Doc ID 023104 Rev 1 1/4 For further information contact your local STMicroelectronics sales office. www.st.com 4+ ~ Electrical schematic EVL6564H-100W 1 Electrical schematic Figure 1.
