The EVB_RT7285CGJ6 is an evaluation board, designed specifically to provide an accurate and efficient power source from a wide range of AC and DC input supplies. This power supply module is suitable for industrial automation, audio/visual, motor control and other general purpose applications. EVB_RT7285CGJ6 offers single, dual, and triple output configurations, high efficiency, and features a high accuracy over-voltage protection (OVP) feature.

EVB_RT7285CGJ6 application field includes battery backup systems, audio/video systems, motor control and power regulation, LED lighting, telecommunications, computers and other consumer electronics. It is also suitable for machine automation applications, such as power conversion, switching, and speed control. The board provides three independent outputs from a wide range of AC and DC input supplies, and supports three different output current levels of 5A, 10A, or 15A.

The EVB_RT7285CGJ6 evaluation board has a positive synchronous rectified buck topology, with a wide-angle PFC, with a high-speed current mode controller, allowing it to be quickly and easily adjusted to an appropriate input voltage source. This high-frequency limitation allows for smaller power supply components, which can reduce board space, cost, and component count.

The board features, among other things, an onboard temperature control system, for temperature monitoring and regulation, OVP, for over-voltage protection, thermal warning LED and shutdown capability, for overload, over-temperature, and over-current control, soft-start circuit, for voltage ramp up during turn-on and transient suppression, plus comprehensive under-voltage lockout. In addition, the board is designed to meet international safety, performance, and electromagnetic standards.

The working principle of the EVB_RT7285CGJ6 is based on the incorporated high-frequency PFC controller, which ensures a constant voltage output over a wide range of input voltages and line conditions. The PFC controller regulates the voltage by coupling the output to the input voltage and gives a constant current source to the load. The EVB_RT7285CGJ6 controller also provides a wide range of features such as overload protection, inrush current limiting, overheat protection, and soft start capability, ensuring the safety and reliability of the board.

In conclusion, EVB_RT7285CGJ6 is a high-efficiency, multi-output AC to DC power supply evaluation board, suitable for a wide range of applications. It features universal input and three independent outputs, adjustable current levels, high-efficiency, and features OVP protection. The onboard temperature control system with a soft start circuit, ensures reliable operation, whilst meeting international standards, in all operating conditions.
