Hi Paul,
As per your recommendation, we modified the PMIC layout and additionally connected 200pf capacitor to L4A pin to GND
But then also, We are facing the same problem. same voltage behavior of all DCDC1- DCDC4 as posted before
After removing the 200pf ceramic capacitor from the board and 5V reduced to 4.75 V PMIC start functioning.
But sometimes failed to startup. In 10 attempts 7 times successfully ON and 3 times Not.
What is the concrete solution, Is there any Errata for PMIC TPS65218B101
Pl. reply ASAP.
