Hysteresis-Current-Controlled Buck Converter Suitable for Li-Ion Battery Charger

摘要：

A new hysteresis-current-controlled (HCC) buck converter suitable for Li-Ion battery charger is presented in this paper. The technique adopted in this charger is constant current/constant voltage dual mode, which is decided by the value of internal resistance of Li-Ion battery. This technique will degrade the damage of Li-Ion battery and improve the power efficiency of charger. The Li-Ion battery charger is designed with 0.35-μm CMOS DPQM processes. The simulation results show that the charger works well and confirms with theoretical analysis. The power efficiency of charger can be up to 82％ under the average power of 825 mW. The chip area is only 1.71×1.52mm2.
