STEVAL-ISA077V1

High efficiency synchronous rectifier step-up converter

demonstration board based on the L6920DB

Features

Description

The STEVAL-ISA077V1 demonstration board is

based on the L6920DB which is a high efficiency

monolithic step-up switching converter IC

especially designed for battery powered

applications, thanks to its minimum startup 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 voltage of 1.8 V, which is

enough to supply even the most advanced ASICs

and microprocessors.

The high switching frequency allows the user to

choose small inductors and output capacitors for

their designs. Supervisory functions include

reference voltage, low battery detection, and

shutdown, which are provided with overcurrent

protection.
