I am trying to use a piezoelectric element to charge a li-ion battery. Basically my set-up so far is the following:
My piezoelectric element is connected to a LTC3588-1 module (1568-1038-ND) which outputs a 3.3V. I am trying to charge a single cell li-ion battery that requires 4.2V for charging. I am missing a component that takes the 3.3V output and converts in into a 4.2V for battery charging. Note the li-ion battery capacity will be pretty small, between 50 and 150 mah.
I searched all over and I cannot find components that work.
Ps. I am in my last year of mechanical engineering, I am not too familiar with electrical engineering.
