EVL6562A-TM-80W 80 W high performance transition mode PFC evaluation board Data Brief Features ■ Line voltage range: 88 to 265 VAC ■ Minimum line frequency (fL): 47 Hz ■ Regulated output voltage: 400 V ■ Rated output power: 80 W ■ Maximum 2fL output voltage ripple: 10 V pk-pk ■ Hold-up time: 20 ms (VDROP after hold-up time: 300 V) ■ Minimum switching frequency: 35 kHz ■ Minimum estimated efficiency: 92% (VIN = 90 VAC, POUT = 80 W) ■ Maximum ambient temperature: 50 °C ■ PCB type and size: single side, 35 µm, CEM-1, 108 x 57 mm Description The L6562A is a current-mode PFC controller operating in transition mode (TM). With the same pin-out as its predecessor L6562, the L6562A offers improved performance mainly in terms of efficiency and noise immunity. This board implements an 80 W, wide-range mains input and a PFC pre-conditioner suitable for ballast, adapters, flat screen displays, etc. October 2007 Rev 2 For further information contact your local STMicroelectronics sales office. 1/6 www.st.com 6 Electrical specification and performance 1 EVL6562A-TM-80W Electrical specification and performance Figure 1.
