What is the maximum sink current of the ACOK and STAT pins on the MP2672A? I’d like to know if it is sufficient to turn on an LED or if I need to use a MOSFET.
Thanks!
Hello Weston,
I was looking through the MP2672A datasheet (page 9) and saw the following condition on the sink current through the ACOK and STAT pins:
This would be the typical sink current.
In the EVB schematic (and under typical applications), there is usually an LED connected as well as a 2kΩ resistor connected. Here is the EV2672A datasheet so you can view the full schematic and BOM for yourself.
These are the LEDs that are used in the EVB for further reference so you can get an idea on the current they draw:
Hope this provided some insight.
Best,
Krishan
