Introduction to CDB5461AU Evaluation and Demonstration Boards and Kits

The CDB5461AU evaluation and demonstration kits provide developers and OEMs with a convenient means to quickly evaluate and demonstrate the functional support of the NXP CDB5461AU device. This demo kit, which is available from NXP and various other distributors, serves as a starting point for those who are interested in using the CDB5461AU in their designs.

Application Field of the CDB5461AU

The CDB5461AU is an integrated intelligent power management IC (IPM) designed to provide a flexible, highly reliable and cost-effective solution to monitor and control both voltage and current in a wide range of DC applications – from HDD and PC/server to embedded control. By integrating multiple power management functions on one integrated circuit, the CDB5461AU enables developers to reduce overall system cost and size.

The CDB5461AU is suitable for both industrial and commercial applications and can be used in many applications such as computer peripherals, motor control, consumer electronics, telecommunication equipment and networking systems etc. In particular, the CDB5461AU offers a wide input voltage range and is capable of both step-down and boost conversion, making it ideal for applications where wide input voltage range is required.

Working Principle of the CDB5461AU

The CDB5461AU is a non-isolated, 8-phase, buck-boost synchronous converter. It is equipped with an integrated, high-efficiency power stage that can drive up to 12A output current. It is capable of controlling voltage and current output parameters in accordance with user-programmed set points, and responding to analog and digital input signals from the system controller.

The device also comes with an intelligent power management (IPM) block that provides high-efficiency, low-power operation. The IPM block consists of several blocks, such as the voltage regulator (VR), current sensor (CS), current limit (CL), over current (OC), voltage divider (VD) and thermal monitor (TM). It also includes a flexible power control block with programmable current limit, multiple operating modes, and over voltage and current protection.

In addition, the CDB5461AU is equipped with multiple signal interfaces, including SPI, I2C, and CAN bus. These interfaces are used to provide communication between the device and the system controller, in order to exchange commands and data for power management tasks.

Conclusion

In summary, the CDB5461AU is a high-performance, power management IC designed to provide low-cost and highly reliable solutions for monitoring and controlling voltage and current requirements in a wide range of applications. The device comes with integrated intelligent power management block, a highly efficient power stage and a wide range of communication interfaces. The evaluation and demonstration kits provide a convenient means to quickly evaluate and demonstrate the functional support of the CDB5461AU device.
