2.5 A Companion Charger for Rapid Charging

Datasheet

Revision 3.2

25-Feb-2022

CFR0011-120-00 Rev 5

1 of 37

General Description

DA9155M offers a small solution that can be easily added on to existing main charger circuits and

solves the heat dissipation problem created when the rapid charging feature is adopted. DA9155M is

compatible to all rapid charging technologies using high voltage input.

DA9155M features a Buck converter capable of 2.5 A constant output current and regulates the

output current with ±5 % accuracy for single cell Li-Ion batteries. Current sensing is performed with a

fully integrated circuit.

The peak efficiency of the Buck converter is 92 %.

Key Features

■ Input voltage 4.3 V to 13.5 V
