The L6920DB is a high efficiency monolithic step up switching converter IC especially designed for battery powered application. (Conversion from 1 to 3 alkaline, NiMH, NiCd battery cells or 1 Li-Ion).
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.
