TPS62826EVM-794

The TPS62826EVM-794 is an evaluation board that has been developed to enable designers to test and evaluate the capabilities and features of the TPS62826, a synchronous buck DC/DC converter. The board’s basic functionality is to deliver up to 3A of output current from a 3.3V DC input with an adjustable output voltage range from 1.21V to 3.1V.The first step in evaluating the board is to determine its intended application field. The board is well suited to applications where size and power density are paramount. It is capable of delivering up to 94% efficiency so the power dissipated in the form of heat is minimal. This makes it a great choice for applications that need to work in compact spaces, such as mobile devices or computers. The board has been designed to meet stringent energy and environmental standards, as well as have a small, overall footprint, allowing it to be used in applications where space is limited.The second step in evaluating the board is to understand its working principle. The TPS62826EVM-794 is a synchronous buck converter that utilises a two-step conversion process to generate the desired output voltage. The first step involves the switching regulator controlled by an internal linear voltage regulator (Vin >VDD) to generate a high-accuracy 1.5V output. It then uses an external transistor to reduce the voltage through step-down regulation via Pulse Width Modulation (PWM) regulation.The board offers a number of protections and features, which are enabled externally by attaching external components. These include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), thermal shutdown (TSD), soft-start, and auto restart. Additionally, the controller has see-through current modes which can optimize the output ripple for low noise applications.In conclusion, the TPS62826EVM-794 evaluation board is an ideal choice for applications where size and power density are of high importance. It is capable of delivering up to 3A of output current from a 3.3V DC input with an adjustable output voltage range from 1.21V to 3.1V. It offers features such as over-current and over-voltage protection, as well as thermal shutdown and soft-start. Additionally, the evaluation board has been designed to meet stringent energy and environmental standards.
