Flyback power supply design pdf
WebAdding a smart high-side switch to a design leads to a smarter and more robust solution for driving capacitive, inductive, and LED loads. Low-side switches connect the load to ground instead of providing a connection between a power supply and the load. By including an integrated flyback diode, low-side switches help eliminate inductive load
