PMIC, or Power Management Integrated Circuits, are a family of devices used to convert and regulate the power source of a device. A PMIC can provide several types of power: AC, DC, solar, and battery. UCC39002DR is an example of a specialized PMIC. It is used for electromagnetic interference (EMI) filtering in automotive applications. This application note explains the features and working principles of the UCC39002DR.

Features of the UCC39002DR

• Ultra-low Rds(on) EMI Filtering: The UCC39002DR is designed for ultra-low EMI filtering, with on-resistance (Rds(on)) as low as 10mΩ.
• High-efficiency Power Delivery: The UCC39002DR is designed with multiple power paths and ultra-low Rds(on) to deliver high-efficiency power to different devices in the system.
• High operating temperature range: The UCC39002DR is designed to operate at high temperatures, up to 150°C, allowing it to be used in automotive applications.
• Small package: The UCC39002DR is available in a small package, the TSSOP-8, which allows for compact PCB designs.

Application fields of the UCC39002DR

The UCC39002DR is designed for EMI filtering in automotive applications. automotive applications require a high level of EMI filtering and the UCC39002DR is ideal for such applications due to its ultra-low Rds(on) and high operating temperature range. The UCC39002DR can be used in systems with DC/DC and AC/DC converters to provide both EMI suppression and power conversion.

The UCC39002DR can also be used in other applications where a high level of EMI filtering is required, such as industrial and telecommunications equipment. The UCC39002DR is also suitable for applications where space is limited due to its small size.

Working Principle of the UCC39002DR

The UCC39002DR is a specialized PMIC that is designed to provide EMI filtering in automotive applications. It works by providing multiple power paths and low on-resistance (Rds(on)) to reduce EMI noise in the system. The UCC39002DR uses an active phased array technology to provide optimal EMI filtering performance at high temperatures.

The UCC39002DR provides multiple power paths to reduce EMI noise. It uses a “follow the leader” power path control technology to ensure that the EMI filtering performance is always optimal. The power paths are connected to the output of each power device. The device is designed to redirect the current to the path with the lowest on-resistance (Rds(on)) in order to deliver the most efficient power delivery.

The UCC39002DR also uses a low on-resistance (Rds(on)) to reduce EMI noise in the system. The low on-resistance (Rds(on)) reduces the amount of electrical noise in the system as the current passes through the device. This helps to reduce EMI noise in the system and ensures that the system meets EMI emission requirements.

The UCC39002DR is also designed to operate at high temperatures, up to 150°C, allowing it to be used in automotive applications. This allows the device to operate in hotter operating temperatures while still providing optimal EMI filtering performance. It also helps to reduce the overall power consumption of the system.

Conclusion

The UCC39002DR is a specialized PMIC designed for applications requiring EMI filtering. It features multiple power paths, ultra-low Rds(on), and high operating temperatures, making it ideal for automotive applications. The UCC39002DR provides optimal EMI filtering performance and helps to reduce power consumption in the system. Understanding the features and working principles of the UCC39002DR will help you make the most of this powerful device in your designs.
