EVB_RT9088GQW evaluation board is designed to be used with the RT9088GQW control IC for off-line switched-mode power supply (SMPS) applications, such as those used in televisions, computer monitors, gaming consoles, mobile devices, and other electronic products. This evaluation board is a versatile platform for evaluating the performance and quality of the RT9088GQW control IC in a realistic and cost-effective manner.

The RT9088GQW evaluation board consists of a DC/DC Boost pre-regulator, a Flyback PFC post-stage, an EMI filter, a opto feedback phase-shift full-bridge rectifier, a variable frequency 42V/1A synchronous buck regulator and a Level3/Level4 of EMI reduction circuits. The board includes a back cover to protect the components from external interference. The RT9088GQW is a digital control IC with integrated self protection features that are programmable through external pins.

The RT9088GQW evaluation board is designed to provide output power levels up to 3.5A and is capable of supporting a variety of input voltage applications ranging from single phase (AC 85-265V) to multi-phase (up to 3 phase). The board also features a level 4 EMI filter, which reduces conducted and radiated emissions, resulting in higher efficiency and quieter operation.

The evaluation board features a flexible control interface that allows for PC-based setup and monitor the performance of the RT9088GQW control IC. The board supports real-time monitoring of operating temperature, output voltage and current, and other operating parameters. It also comes with a graphical user interface for monitoring and controlling the performance of the device in real-time. Additionally, the board supports PC-based programmable parameters, such as frequency switching level, voltage cancellation, overvoltage protection, and overcurrent protection.

The working principle of the RT9088GQW evaluation board is based on the PFC post-stage. The PFC post-stage is an integrated flyback convertor for post-regulation of pre-regulated power. The pre-regulated power is applied to the PFC post-stage which will then perform active waveform shaping to shape the input power waveform into a suitable form for the output stage. The output stage includes an opto feedback phase-shift full bridge rectifier which will then rectify the output voltage. The output voltage is then regulated by a Synchronous buck converter, implemented with an RT9088GQW control IC. The RT9088GQW includes integrated self protection features, making the evaluation board a reliable solution for providing powerful and stable output power.

In summary, the RT9088GQW evaluation board is an ideal platform for evaluating the performance and quality of the RT9088GQW control IC in DC/DC & AC/DC (Off-Line) SMPS applications. The board is designed to provide output power levels up to 3.5A and is capable of supporting a wide range of input voltages. The board also features a level 4 EMI filter for improved safety and reduced EMI emissions. The board is also equipped with a flexible control interface for real-time monitoring and programming of the control IC.
