Power Management Integrated Circuits (PMIC) often serve a variety of important tasks, such as voltage regulation, energy conversion, and system protection. PMICs also help to improve power efficiency in today’s electronics, from small handheld devices to large industrial systems. In this regard, the SC4524D(S)ETRT, is a highly-intelligent device for controlling the power and voltage to the system. It integrates both a synchronous buck and a linear regulator on one chip, creating a single, highly efficient solution.

Application Field

The SC4524D(S)ETRT can control a variety of input voltages and output currents, making it a versatile choice for many types of applications. It operates with a supply voltage up to 16V, regulating up to 8V at over 5A of output current. This makes it ideal for applications such as battery chargers, automotive engine control, DC-DC converters, and many others that require wide input voltage ranges. It also features integrated gate drivers with programmable pre-charge settings, allowing it to adjust the output voltage to meet the load’s requirements.

Working Principle

The SC4524D(S)ETRT utilizes two modes of operation to achieve its wide range of output voltages and currents: synchronous buck and linear mode. In synchronous buck mode, it uses a high-frequency switching converter to convert an input voltage to a regulated output voltage. This allows it to handle higher voltages and currents at higher efficiencies than traditional linear regulators. In linear mode, it utilizes a linear regulator to achieve lower output voltages. This allows it to achieve higher efficiency at lower load currents—something that cannot be achieved with a traditional linear regulator.

The SC4524D(S)ETRT also features a built-in overcurrent, overvoltage and overtemperature protection mechanism to ensure that the system is protected from any unexpected inputs or errors. Additionally, it has an integrated output discharge circuit designed to prevent any overvoltage issues when the system is not in use. This makes it a highly reliable and efficient voltage regulator for a variety of applications.

Conclusion

The SC4524D(S)ETRT is an intelligent device for controlling power and voltage to the system. It boasts a wide range of input and output voltages and currents for applications such as battery charging and automotive engine control, as well as integrated protections and a discharge circuit for system reliability. By utilizing both synchronous buck and linear modes, it has emerged as the choice voltage regulator for many engineering applications where reliable performance and high efficiency are required.
