Flyback current

WebFlyback topologies are practical and lowest cost for systems up to power levels of 100W. Above this power level other methods such as forward converters become more cost effective, due to reduced voltage and current stresses on the devices. Flyback transformer design is a somewhat iterative process, due to the number of variables involved, but it WebThis reference design is for a highly efficient, flyback, 5V Class 3 powered device (PD) with a wide 9V to 57V auxiliary input. The design features the MAX5969B as its controller. The design also uses the MAX5974D, which controls current-mode PWM converters and provides frequency foldback for both the auxiliary input and power over Ethernet (PoE)
