Description

This reference design features four isolated bias power supply designs using different topologies such as PSR flyback, push-pull, LLC resonant, and isolated DCDC module. These topologies provide specific benefits but at the same time the topologies come with trade-offs. An ample comparison of these topologies is done using four hardware designs while keeping the electrical parameters as similar as possible. The input and output voltage of these designs are 15V and the maximum load current is 100mA.
