TPS43350EVM Application Field and Working Principle

TPS43350EVM is an evaluation module developed by Texas Instruments that can be used for DC/DC and AC/DC (Off-Line) SMPS. It provides users with a great tool for testing and evaluating the functionalities and features offered by the TPS43350EVM control chip. The TPS43350EVM can help users optimize system performance within a predetermined power envelope.The TPS43350EVM DC/DC & AC/DC SMPS offers adjustable output voltage and current from 3.3V to 5.5V and adjustable switching current from 2A to 8A. It is a highly efficient design and provides high performance switching and tight regulation over the full load range. The TPS43350EVM evaluation board is integrated with all the necessary components for the proper operation of the TPS43350EVM control chip and can be used with either AC or DC voltage sources.TPS43350EVM operates in fixed on-time mode. The variable off-time concept allows for fast transient response and cycle-by-cycle overload protection with short circuit protection. The extended on-time protection allows for thermal protection by limiting the current preload or pulse-width. The TPS43350EVM also features automatic burst mode operation for reduced power consumption at light loads. It has built-in over-voltage and under-voltage protection as well as over-temperature protection. The TPS43350EVM also comes with a soft-start time-out protection to minimize inrush current.The TPS43350EVM evaluation board operates over a wider temperature range than the standard limit of 0 ˚C to 70 ˚C. It offers short circuit protection, current limit protection, thermal shutdown and an enable feature. The current limit always adjusts to the temperature of the device, thereby allowing proper switching performance. The TPS43350EVM also has an enable function which can be controlled externally using a digital signal.The TPS43350EVM DC/DC & AC/DC SMPS evaluation module is an attractive solution for many applications ranging from portable electronics, automotive, consumer, industrial and medical electronics. Its adjustable output voltage and current combinations provide the necessary flexibility for various applications and its highly efficient design and features make it a favorable solution for customers. The ease of use enabled by the off-the-shelf evaluation board makes it a good choice for those who are looking to quickly evaluate and test the performance of the TPS43350EVM. Additionally, the advanced features of the TPS43350EVM make it a good solution for applications with heavy power dissipation and need for small form factor solutions.
