Introduction

ACT8828 is an energy-efficient, high-performance and three-in-one Power Management Integrated Circuit (PMIC). It is designed for applications such as tablets, notebook PCs, telecom equipment and industrial systems. ACT8828 integrates buck / boost DC-DC converter, single-channel Li-Ion battery charger, load switch, and load-discharge circuit into the same package. All the input voltage ranges are 2.7 V to 5.5 V, which covers almost all battery and USB input sources.

Application Field

The ACT8828 is a cost-effective PMIC solution with a wide range of applications. It includes an integrated DC-DC converter with both buck and boost modes, and a Li-Ion battery charger. With these two devices combined, it is ideal for portable end-applications, such as tablets, notebooks, netbooks and other mobile devices, as well as industrial systems.

The ACT8828 can provide up to 10A of load current with a load voltage from 0.9V to 5.5V in its buck mode, making it suitable for various system architectures. In its boost mode, it provides up to 100mA of output current with a slew rate of 0.89V/ms. It is designed to fit low-power applications such as consumer electronics, medical, communications and more.

The high efficiency Li-Ion battery charger is capable of charging any single Li-Ion battery at up to 5A. It also comes with support for advanced battery-charging protocols such as BC1.2, MTK BC, TRSW and so on. The charger also includes integrated input current limit and thermal shutdown, enabling a safe and reliable charging experience.

Working Principle

The ACT8828 PMIC operates within an industry-wide digital PMIC control architecture that provides high flexibility, reduced power consumption and increased reliability. It has digital control blocks on the DCDC and Battery charger that include CC/CV mode to ensure constant current and constant voltage charging, over voltage protection and over temperature protection as a few.

The DC-DC converter has a wide output voltage range from 0.9V to 5.5V in buck mode and from 1.5V to 5.5V in boost mode. In Buck mode, the converter is capable of providing up to 10A output current, and in boost mode up to 100mA output current.

The Li-Ion battery charger is designed to charge any Li-Ion battery from 0% to 100%. It has an input voltage range of 2.7V to 5.5V, and is capable of providing 5A charge current.

The ACT8828 also includes a combined boost-discharge and load switch, which can enable and disable charge and discharge operations. The boost-discharge switch has a maximum current capability of 2A.

Conclusion

The ACT8828 PMIC is an advanced power management integrated circuit (PMIC) with a short transition time between operation modes, high efficiency and high power. Its integrated DC-DC converter, Li-Ion battery charger, boost-discharge and load switch enables flexible configurations and system architectures, making it suitable for a wide range of applications in the consumer electronics, medical, telecom and industrial domains.
