Hi teams:
VIN=24V; Load: no load;
1. First ground the EN pin of the chip (remove r215), and then test the power consumption of the whole machine at 5.4ma. Then I cut off the VIN pin of the chip, and then test the power consumption of the whole machine at 2mA again.
2. I think the sleep power consumption of the specification is 24ua, as shown in the figure below is our design scheme. Please evaluate whether there is a problem with our design scheme and can not trigger the low-power mode.
Power consumption of EN pin grounding test machine:
Power consumption of the whole machine tested after removing the VIN pin of the chip:
