2.5 A Companion Charger for rapid charging

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 such as Qualcomm Quick Charge™ 2.0 and 3.0 as well

as MediaTek PumpExpress™.

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

output current with ±5% accuracy. Current sensing is performed with a fully integrated circuit.

The peak efficiency of the Buck converter is 92%.

Key features

■ Input voltage 4.3 -13.5 V

■ Input voltage monitoring

■ Buck converter with output current regulation

□ Output current 2.5 A

□ ±5% current regulation accuracy

□ Selectable switching frequency

■ Fault detection (V

IN and VBAT monitoring)

■ Safety timer

■ Junction temperature monitoring

■ -40 to +85 °C temperature range

■ WLCSP, 0.4 mm pitch

Applications

■ Companion charger in smartphone and tablet

platforms
