Hi Team
We are using TPS54318 in our design. Please clarify below.
1. Refer Image attached. Why pull up resistor is not placed at PWRGD pin when connected to enable pin of subsequent regulator.
2. Refer Image attached. I placed 100K external resistor between PWRGD and EN of subsequent regulator. My requirement is 2nd device should be disabled until 1st output is generated. What will be state of 2nd device EN pin until 1st output voltage is generated?
3. How to keep the 2nd device disable until 1st output voltage is generated?
