The TPS5625EVM-105 is a DC to DC synchronous rectified buck converter evaluation module used for a variety of power solutions. It is designed primarily for applications involving non-isolated offline ac/dc supplies up to 24V input (mains) voltages, or non-isolated offline DC/DC supplies from 3.3 V to 12 V. The TPS5625EVM-105 is also suited to be used in other power supply use cases.

The TPS5625EVM-105 supplies improved power conversion efficiency and optimized phase margin behavior in comparison with other asynchronous buck converters. It features a patented soft-start mode, a pulse-skipping mode and a low-power linear-regulator mode that can be used for light-load operation, making it a prime choice for wide input voltage and moderate output current applications.

The TPS5625EVM-105 is based on Texas Instruments TPS5625 controller, a high-performance synchronous buck converter designed to meet the demands of very high power applications. It is fully integrated with all the functions necessary to power a wide range of industrial, automotive, computing, and consumer applications.

The TPS5625EVM-105 has several key features that make it a suitable choice for many different use cases. It has a high operating frequency up to 1 MHz, high-speed transient response, wide operating voltage range and high efficiency up to 94%. It also has an integrated bootstrap gate driver to enable high-side MOSFET control, as well as a quiet-mode stop function to reduce no-load power draw. The module is equipped with a low-cost synchronous dc/dc controller IC and integrated power-stage MOSFETs for a complete and cost-effective solution.

The working principle behind the TPS5625EVM-105 is that the periodic waveforms of the current and output voltage are controlled and synchronized so that ripple current and voltage on the input are minimized and output performance is improved. The system controller includes a synchronous rectifier driver to control the switching of the MOSFETs. This ensures that the output voltage is regulated to within a certain accuracy.As the TPS5625EVM-105 is a buck converter, the output voltage is always lower than the input voltage.

The TPS5625EVM-105 is a versatile solution, with a wide range of applications in both AC/DC and DC/DC power supplies. It can be used for a wide variety of power solutions, such as LED lighting, consumer appliances, industrial equipment, and automotive applications. It is suitable for both non-isolated offline supplies and isolated offline supplies. The TPS5625EVM-105 is a stellar choice for power engineers looking for improved efficiency, higher power, and cost savings.
