Other Parts Discussed in Thread: CSD19534Q5A
Tool/software:
HI,Team.
Currently, an isolated flyback power supply is constructed using LM5022, with an input voltage of 10.8 to 31.2V and an output voltage of 12V at 2A. The CSD19534Q5A is used as the switching transistor with an efficiency of 70%. The turns ratio of the isolation transformer is NP:NS=1:3. Due to a change in output power from 2A to 2.5A, the question is how to calculate the power dissipation of the switching MOSFET. Thank you.
