TPS2491: TPS2491: TPS2491 Startup using Pin 1 EN Part 2 Solved

Part Number: TPS2491

Hi,

i got the new PCB . It worked better then the first one. I was able to turn on power bx EN Pin up to a load of 18 Ohms. On higher loads i could not turn on.

After I removed the 330µF Caps on the output  the system worked as i wanted it to.

It can be switched on and of via EN Pin up to loads of 8 Ohms ~3A.

And turn of at 5 Ohms.

So I am fine with this.

Greez,

Linus
