TPS82693EVM-207 is an evaluation board containing the innovative TPS82693 as a highly efficient and high-performance power solution for the DC/DC & AC/DC (Off-Line) SMPS. It is built with advanced circuitry to meet the current and future power needs for industrial, communications, computing, consumer, and medical applications.

TPS82693 EVM-207 is engineered for excellent power conversion efficiency, integration, and minimized solution size and cost in applications requiring single-output flyback, forward, and half-bridge high-voltage converters with multiple low-voltage outputs and line compensation. It is also suitable for use in higher voltage applications such as telecom and server systems.

The TPS82693 includes feature-rich functions, such as a digitally programmable current limit, remote sense, auto-restart capabilities, as well as integrated protection against over-current, overload, and overvoltage conditions, making the device suitable for broad range of industrial and medical equipment. Moreover, TPS82693’s proprietary adaptive on-time control helps optimize the loop design and minimize the stress on the off-line converter such as ringing or line cycling.

The TPS82693 EVM-207 application board contains all the circuitry needed to evaluate the TPS82693 regulated off-line switchmode Power Supply, as well as to control and monitor its performance. It is designed with easy-to-use onboard components and connectors, eliminating the need for external components.

The board contains a pre-programmed microcontroller used for system monitoring, parameter setting, and on/off control. It also has onboard decoupling and filtering components, enabling quick and easy configuration of high or low-side sensing, remote on/off control, and thermal protection.

The TPS82693EVM-207 works on the principle of synchronous rectification. It uses a pair of MOSFETs to switch the main power transformer in both directions, and draws power stored in the transformer primary during most of the input cycle. During this time, the turns ratio of the transformer core is used to store the energy of the pulse-width modulation (PWM) signal application.

The rectified voltage is supplied to the power supply, which is further regulated by the PWM controller with constant voltage & current mode, and monitored by an analog-to-digital converter (ADC) and temperature and current sense comparators for better protection. The external components provide an over-voltage and over-temperature protection. The voltage and current sense signals are connected to the MCU enabling real-time monitoring on operating parameters.

The TPS82693 EVM-207 evaluation board effectively reduces design cycle time for developing power supplies used in applications such as industrial, communications, computing, consumer, and medical applications. This ‘plug and play’ board is an ideal tool for system engineers to test their applications and understand the TPS82693 EVM-207 Performance Characteristics.
