Lithium-Ion battery charge IC supports large-current charging

RENESAS R2A20057BM lithium-ion (Li-ion) battery charge controller IC for mobile devices integrates a step-down dc-dc converter and supports 2A large-current charging in very small package. Device reduces the mounting area by integrating multiple power MOSFETs and charging circuits in a single chip, using a wafer-level package, a packaging technology that can also supply large amounts of current due to reduced package resistance.
