Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design.
The flyback converter is an isolated switching power

Many AC powered systems above a certain power consumption level require power factor correction (PFC).
This is demanded by either utility companies or by governments. PFC sits right at the
Figure 1: Example PLD, with 12 inputs, 8 product terms and 4 macrocells
PLDs can have hundreds of macrocells with up to 16 product terms driving each macrocell. The AND and OR gates within the product terms can be interconnected to form highly flexible custom logic functions. The macrocells are typically clocked, and their outputs can be fed back into the product term array. This allows state machines to be created.
In most microcontroller architectures, there is a ‘smart' CPU surrounded by a set of relatively ‘dumb' peripherals.
Peripherals have limited functions; converting data from one form to
Wouldn't it be nice to save 25% to 30%, or even more, in circuit board power dissipation in your next design? While for some designs such a savings would just be nice to have, for others it's
