TPS51125EVM: Dual-Synchronous, Step-Down Controller with Out-of-Audio™ Operation and 100-mA LDOs

The TPS51125EVM from Texas Instruments is a highly integrated evaluation module designed for testing the performance of the TPS51125, a dual-synchronous, step-down controller. This advanced power management IC is tailored for notebook and ultrabook applications, providing efficient, adaptive power supply solutions. The TPS51125EVM allows designers to assess the full capabilities of this controller in a practical, real-world setting.

The TPS51125 is a feature-rich solution offering two voltage rails with adjustable outputs from 2 V to 5.5 V, capable of delivering up to 8 A of continuous output current. The controller operates with a quasi-fixed frequency of 340 kHz that helps maintain a balance between efficiency and component size. It also includes a 100-mA low dropout (LDO) linear regulator for additional peripheral supplies.

One of the standout features of the TPS51125 is the Out-of-Audio™ operational mode, which reduces electromagnetic interference (EMI) and noise concerns when the system enters low-power audio playback modes. This makes the TPS51125EVM an excellent choice for applications where noise-sensitive analog circuits, such as audio codecs, are in use.

The evaluation module includes a variety of protection features, such as overvoltage, undervoltage, and overcurrent protection, ensuring the longevity and reliability of the end application. Additionally, the TPS51125EVM features power-good signals and thermal shutdown to further enhance system safety.

With its comprehensive set of features, the TPS51125EVM is an invaluable tool for engineers looking to optimize their power management designs. Whether it's for testing the performance, experimenting with different load scenarios, or simply understanding the operational characteristics of the TPS51125 controller, this evaluation module is an essential asset for any power supply development project.
