Description

The L6920DB is a high efficiency monolithic step

up switching converter IC especially designed for

battery powered application.

Package is MSOP8 in order to minimize PCB

space. It requires only three external components

to realize the conversion from the battery voltage

to the selected output voltage.

The minimum output voltage is 1.8V: suitable to

supply the most advanced ASIC and µP.

High switching frequency allows for a low profile,

small sized inductor and output capacitor to be

used.

Reference voltage, low battery detection and

Shutdown are provided together with over current.
