Adds 11W Charging Power
DA9155M offers a small solution that can be easily added on to existing main charger circuit designs and solves the heat dissipation problem created when the rapid charging feature is adopted in a system. It is compatible to all rapid charging technologies. DA9155M is added in parallel with the main battery charger to solve the thermal issue.
DA9155M features a Buck converter capable of 2.5 A constant output current with an accuracy of ±5%. Current sensing is performed with a fully integrated circuit. The peak efficiency of the Buck converter is 92%.
