Hello everyone,
Please consider we have an LMR16006YQ5 setup to supply 5V from Battery voltage input (6V-45V).
We have a fault condition where, through a 4.7K Ohm resistor, the 5V rail may be pulled up to the battery voltage, as shown here:
This would cause a reverse current of ~4mA to flow back through the buck converter.
Also note that this could be happening during a very light load condition, where the buck converter is supplying less than 30uA.
Q.) Will this cause damage to the buck converter?
Best wishes,
Tony
