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