Introduction

AI Translation

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 AP. 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.

The L6920DB is a high efficiency, low voltage step-up DC/DC converter particularly suitable for 1 to 3 cells (Li-Ion/ polymer, NiMH respectively) battery up conversion. These performances are achieved via a strong reduction of quiescent current (10μA only) and adopting a synchronous rectification that implies also a reduced cost in the application (no external diode required). Operation is based on maximum ON time - minimum OFF time control, tailored by a current limit set to 800mA.
