Dear Sir, please answer
I use TPS61221. Input voltage 1.7 - 5.5V. I out = 40 mA. Uout = 3.3V. Temperature from minus 40 to plus 60 C. Battery application!
If to set "Low" to EN input, then converter stops working and input voltage (in my case it is 1.7 V) "goes" to the out.
Whether there is a similar chip, that out voltage will about 0 V, if to set "Low" to EN input?
