Hello,

any offer,advice for boosting 1-cell Alkaline Battery to 3 to 3.6 volt that can handle minimum load 500mA and goes up to 800mA ?

thanks

The engineer supporting this part is currently out of office. Let me answer for now: 500mA load at 3V input will become >1A dc at 1.5V input, and the switch peak current is way higher than the 1A limit. So, it can not support your load.

You may consider TPS61029, which can handle higher power.

TPS61099 can't support this output current as the current limitation. I would suggest TPS61021A.
