Results forLP4023H

The LP4023 is a standalone 1-cell switching battery charger providing up to 2A charge current to the battery from 4.1V to 6.2V input voltage. The charge current is programmable by a resistor connected from lSET to GND. The charge can be enabled and disabled from lSET pin. The LP4023 operates at 1.2MHz switching frequency allowing a small-size 1uH inductor for 2A fast charging. The LPS patent-protected integrated current sensing and control technique eliminates external sensing resistor and allows high charge efficiency, low BOM cost and very small footprint.
