LM5034: Questions on device

Alfred Logico

Part Number: LM5034

Hi Team,

My customer is planning to use our LM5034. They have a couple of questions below:

1. Frequency domain of the low pass filter of the feedback pin? Need frequency response of LM5034 for current sharing. They want to know the frequency response of bode plot “from feedback(Comp1 and 2) to Duty”.

2. Plan to have 5 ACF power stages, group 1 will control by the output 1 of IC, group 2 will be controlled by output 2 of IC

- Can each output support multiple power stages?

- If it can, how can the current sense of each stage be used by the CS input of the LM5034?

Thanks!

Best Regards,
Alfred
