This note describes the characteristics and the features of a 65 W reference board, wide-range input mains, AC-DC adapter using the L6566B controller. The peculiarities of this design are the low standby input consumption (<200mW @ 265Vin AC), low cost and small size.
The topology of this converter is the classical Flyback working in continuous and discontinuous conduction mode at fixed frequency. The controller, the new L6566B, is an extremely versatile current mode primary controller ICs.
The nominal switching frequency, 80 KHz, has been chosen to get a compromise between the transformer size and the converter efficiency.
