Hi there,

Can we add a diode between battery and input to boost converter?

What I wanted to achieve is taking the input voltage to a level so that boost converter does not go out of regulation if input voltage increases by a little.

Typical case :
If battery voltage is 3.8V and boost converter goes out of regulation after 3.4V

In that case if I put diode to drop input voltage to 3.0V. What impact will this have on performance of Boost converter.

Any theoritical base would be appreciated. Thanks.
