The TPS84210EVM-002 is a Demonstration, Development, and Evaluation platform for the TPS84210 Step Down Converter. This step down converter is an off-line low power AC/DC SMPS device used to provide power to loads with an input voltage of 10-16V and output voltage from 1.2-15V.

The TPS84210EVM-002 evaluation board is designed to allow evaluation of the device over the operating range, experiment with a wide range of components and to allow for various optimizations. It consists of a 32-pin QFN TI power stage, a controller and support circuitry and demonstrates the performance and features of the TPS84210 controller in typical application. This evaluation board also features a connect/disconnect switch to disconnect the input voltage from the board.

The operating principle of the TPS84210EVM-002 is based on a two-switch topology which enables low cost and high efficiency operation in standby and light load conditions. In light load operation, the converter operates in a pulse-width- modulation (PWM) mode where it controls the longer switch (high side) and reduces the on time for both switches to maintain a constant output voltage. The longer switch is modulated in PWM mode by a control circuit, and the shorter switch (low side) is modulated in a hysteretic current-mode-control (HCP). This provides a fast response time to the output voltage variation and allows the converter to achieve high output accuracy and stability.

The TPS84210EVM-002 is a versatile evaluation platform which allows easy experimentation and optimization with the various load, operating conditions, and components. It has adjustable switching frequency and multiple soft start options for different applications and has over-current and short-circuit protection. This evaluation board can be used for applications such as portable consumer electronics, telecommunication systems, industrial electronics, and lighting systems. It also can be used in automotive applications where a wide range of input voltages and an output current of up to 5A is required.

The TPS84210EVM-002 is also a flexible platform which can be used to evaluate different power architectures such as Single-stage, Flyback, SEPIC, and other power topologies. The platform is designed to allow the user to experiment and optimize with different settings to meet the desired application performance. The board includes an on-board microcontroller which is programmed with a firmware designed to automatically configure the power stage for optimum performance.

In conclusion, the TPS84210EVM-002 is an evaluation platform for the TPS84210 step down converter and is suitable for a wide range of applications. It is designed to allow experimentation and optimization with a wide range of power architectures in off-line DC/DC and AC/DC (off-line) SMPS applications, and has adjustable switching frequency and multiple soft-start options for different applications. With its automatic configurator firmware and integrated over current and short circuit protection, the TPS84210EVM-002 is an ideal platform for evaluating the TPS84210 step down converter.
