Introduction

The ACT8847QM502-T is a high performance System-on-Chip (SoC) PMIC (Power Management Integrated Circuit) tailored for the design of consumer electronics devices. Integrated with a high voltage LDO (Low Drop-Out) regulator, a low voltage LDO regulator, a DC-DC buck converter, and a DC-DC boost regulator, it allows designers to save in the design area, reduce production time and cost, and increase product performance and reliability.The ACT8847QM502-T combines analog and digital power-management technologies and offers total device power consumption management control for an optimum overall system solution. This device can be used for a broad range of applications including PDAs, cell phones (clamshells, camera phones etc.), digital cameras, Bluetooth headsets, portable navigation systems, and other portable consumer electronics where total system power demand management is necessary.

Application Field

The ACT8847QM502-T is designed to support a wide range of applications. As a complete system power manager, it helps designers save space, reduce production time and cost, and increase product performance and reliability. Compared to using discrete components and complex power management design, the ACT8847QM502-T can reduce total system cost and time-to-market and reduce the overall number of components and connections necessary.This device offers comprehensive power functions and can support a range of input voltage configurations. It also features an extensive range of settings and adjustable parameters, providing an ideal solution for a variety of devices.

Working Principle

The ACT8847QM502-T features four primary components: a high voltage LDO (Low Drop-Out) regulator, a low voltage LDO regulator, a DC-DC buck converter, and a DC-DC boost regulator. This device offers comprehensive power functions and can support a range of input voltages.The high voltage LDO is designed to provide power to the buck converter and the rest of the device circuits. It operates with a low quiescent current, making it suitable for battery-powered products. The low voltage LDO is designed for low current, low noise applications for which the load current remains constant.The buck converter is designed to convert high input voltages to low output voltages. It operates at high switching frequencies to reduce component size while providing excellent efficiency and transient performance. The boost regulator is designed to convert low input voltage to higher output voltage. It is adjustable so that the output voltage is set to the desired value.

Conclusion

The ACT8847QM502-T is a high performance System-on-Chip (SoC) PMIC (Power Management Integrated Circuit) tailored for the design of consumer electronics devices. It features a high voltage LDO (Low Drop-Out) regulator, a low voltage LDO regulator, a DC-DC buck converter, and a DC-DC boost regulator, allowing for a complete system power management solution for a wide range of applications. This device is designed to help designers save space, reduce production time and cost, and increase product performance and reliability. With its adjustable operating settings and adaptive controls, the ACT8847QM502-T helps ensure a reliable, optimized power supply for today’s advanced and ever-evolving consumer electronics designs.
