Application Field and Working Principle

The TPS43331EVM is designed for evaluation of the TPS43331 RSENSE dual-channel synchronous controller. This controller is capable of providing up to 1A of continuous current in each channel. It is primarily intended for use in high-speed buck/buck-boost conversion topologies used in various AC/DC and DC/DC power systems. It is especially suitable for applications such as medical equipment, industrial machinery, motor drives, consumer electronics, and automotive systems. The TPS43331EVM supports up to 20V continuous input voltage, making it suitable for a wide range of applications.

The TPS43331EVM evaluation board is provided with all necessary components and features for a quick evaluation of the performance of the TPS43331. It has two MOSFETs, a switching transformer, a buck controller, two drivers to drive the dual-channel synchronous controller, two output voltage and two load current sense resistors. The board also includes a power input section with reverse voltage protection, undervoltage lockout and power indicator LED. All the components are connected on the board and can be easily accessed and replaced if needed.

The evaluation board is designed to enable a user to easily evaluate the performance of the TPS43331 in a wide range of conditions. The user can manually adjust the output voltage and load current by changing the values of the sense resistors. In addition, the board also features optional jumper settings for configuring soft-start, cycle-by-cycle current limit, frequency dithering and light load mode selections. The board also provides LED indications of power good, system faults and OC fault conditions.

The working principle of the TPS43331EVM is quite simple. The input voltage is applied to the board which is then regulated by the MOSFTs based on the signal from the controller. The controller then drives the MOSFETs accordingly to regulate the output voltage and current. The transformer also acts to step down the voltage to the desired level. The output voltage and current can be adjusted by changing the value of the sense resistors. Finally, a number of optional jumper settings can be configured to modify the performance of the board.

The TPS43331EVM is an ideal solution for evaluating the TPS43331 RSENSE dual-channel synchronous controller. It enables users to quickly and easily evaluate the performance of the device in a wide range of conditions. The board also provides all of the necessary components and features for a successful evaluation. Moreover, the board’s simple design and comprehensive documentation make it easy to assemble and use.
