L6920/DB
The L6920/DB is a high-efficiency monolithic step-up switching converter IC
specifically designed for battery-powered applications. The MSOP8 package
minimizes PCB space. It requires only three external components to convert the
battery voltage to the selected output voltage. The minimum output voltage is 1.8
V, suitable to supply the most advanced ASICs and microprocessors.
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
overcurrent protection.
