TPS54335EVM-556

The TPS54335EVM-556 Evaluation Board (EVM) is a powerful, cost-effective way to evaluate the performance of Texas Instruments\' (TI) proprietary TPS54335 buck converter for offline power supplies and point-of-load (POL) power. TPS54335EVM-556 provides designers with a handy platform that they can use to quickly evaluate TPS54335 power performance, adjust parameters and check the output voltages. As a PMBus compliant product, this EVM provides comprehensive and intuitive user-friendly software control.

TPS54335EVM-556 is suitable for applications powered by an input voltage range of 3V to 12V and an output voltage ranging from 1.2V to 12V, maximum current 5A. Applications for this EVM include consumer electronics, computing, telecommunications, industrial boards, ac-dc adapters, high power DC-DC converters, and battery chargers. The EVM includes comprehensive operating mode settings such as Forced PWM, Burst Mode, Forced PFM, and Sleep modes. This board also includes an onboard voltage supervisor (VSUP) for a live load operation.

The working principle of the TPS54335EVM-556 is based on the buck converter. Buck converters use an inductor that stores and releases electrical energy via magnetic flux as current is drawn from the output. The energy is converted either to or from a voltage across an output capacitor. Buck converters are known for their high efficiency because less energy is lost in heat during the conversion process. As current is drawn from the output, the output voltage of the converter declines until the load is fully satisfied. After a certain number of cycles, the average voltage across the output capacitor will reach a steady state that is equal to the control voltage set by gate-drivers on the FETs. This is how the buck converter regulates its output voltage.

The TPS54335EVM-556 is easy to use and offers reliable performance for many applications. With its intuitive user interface and comprehensive features, designers can easily test various parameters and quickly adjust the output voltage. With its comprehensive operation modes, the EVM offers great potential for designers to maximize power efficiency and reduce noise. This user-friendly evaluation board is the perfect choice for designers looking to optimize their power supply designs.
