Part Number: LM5022
Other Parts Discussed in Thread: LM5155

Dear TI,

I need advise for 50W-80W Isolated Capacitor Charger Circuit.

Input Voltage:10V-14V

Output Power:50W-80W (Isolated)

I am going to use LM5022 to constantly charge capacitor. Capacitor should keep same voltage level.

Do you have better solutions other than LM5022?

Thank you, best regards.

Hello,

The LM5155 is an alternative solution. What is the target output voltage? Or do you need output voltage protection?

Are you planning on implementing a flyback topology.

Thanks,

Garrett

Target output voltage is 1000V, output voltage should stay at 1000V as long as input voltage is on. I am planning to implement boost solution.

The LM5155 is going to be the best option.

Thanks,
