Application note
Designing with L6920DB, high efficiency
syncronous rectifier step-up converter

Introduction
The L6920DB is a high efficiency monolithic step-up switching converter IC especially
designed for battery powered applications, thanks to its minimum start-up of 0.8 V, and a
minimum operating voltage of 0.6 V.
It requires only three external components to realize the conversion from battery voltage to
the selected output voltage.
It has a minimum output
