Other Parts Discussed in Thread: LM5163, TPS562231
Hello there,
we want to use LMG5200 for our Powersupply and made our own eval board with some issues.
I ran into that:
finding a solution here:
which was quite tricky. Please update the datasheet.
Anyway now the digital part is our problem.
I saw that you only use LDOs for 5V supply. Is this recommended? We use LM5163 from 60V down to 5V and see some really ugly stuff here. We already killed some LMG5200, probably bei <6V overshoots.
Furthermore I see 10pF to GND in the HI LI lines. Also some 10k pull downs and some 10R in series. Is this recomended too?
(all on the evalboards)
Information of our goal product:
60V Input
55V Output
5A Output
60V are also used to make 5V (LM5163). 5V are used to make 3.3V (TPS562231)
If I forgot something to mention please let me know
Best regards
Marcel
