First, I find it very frustrating when someone designs a web tool that does not allow an exception when it doesn't work. I tried to put the part number in the part number field but the filed does not recognize it and will not allow a more generic description. It will allow "LM3671MF-" but stops me when I type a 3. It only offers a 1.8 or 1.2 So my only option is... "no part number" So I am not going to spend too much time describing my problem until I know this can be seen by forum members.
I have have had five proto boards built, all with LM3671MF-3.3 IC's on them. I have three power rails 5V, and 20V, both behind the LM3671, sourcing 3.3V. Everything comes up fine. But when I take the enable pin low, I still have 300uV @ various voltages of between 600-800mV depending on the board. being sourced by the LM3671.
I am building a battery operated device and chose the LM3671 because of the specified .01uA standby current.
Am reading the data sheet wrong?
800uA seems kinda high for a device that's supposed to work with a single cell battery
Is it possible I got hold of a bad batch?
I can supply drawing and layout once I know this post is going to be read.
Thanks,
