Other Parts Discussed in Thread: TPS54528,
Hi TI
TPS54527DDAR this chip, we found that the power consumption is too large, 12V input and 3.3V output. Even if all 3.3V loads are removed, the 12V input has a self loss of 30mA.
When the power chip is removed, the 12V input port measures the current at UA level;Help explain why this phenomenon occurs?
