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 m, 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.
