This document delves into problems encountered with the TPS65070 power sequencing, particularly when the 1 ms timing is set to Low status, leading to a failure to initiate the power sequence. We aim to explore the potential causes of this issue and suggest possible troubleshooting steps to ensure the DCDC3 output operates correctly. This analysis will benefit engineers working with power management ICs and those seeking solutions for specific power sequencing challenges.

TPS65070Sequence PB_IN I want to know about this time. PB_IN 1msec with Low status , but this device power sequence didn't start. DCDC3
