TPS543B20: TPS543B20

Part Number: TPS543B20

Hi Team, 

I am using in my new design TPS543B20.

 

  1. I need to connect PGD pin to BP pin with 100K resistor, I am right?
  2. How to connect EN pin  - should be floating or should be tied to BP?

Attached my design.

Thanks,

Shlomi

    Shlomi,

    The PDG pin is open drain output. You need to pull it up to some external voltage. BP is a good choice for this, but it could be a different voltage.

    EN is pulled up internally to BP. You can leave it floating. If you need to dissable the TPS543B20 during operation, you will have to pull it down externally with a control signal.
