  EVB_RT7243GQW is a kind of evaluation board, an application field of EVB_RT7243GQW is DC/DC & AC/DC (Off-Line) SMPS. This kind of evaluation board is designed to evaluate and demonstrate the RT7243GQW integrated circuit (IC), which is an off-line power supply controllers manufactured by Richtek. It consists of one-time programmable (OTP) microcontroller which integrated the Maximum Power Point Tracking (MPPT) algorithm.

  The EVB_RT7243GQW is formulated with SOP-8 which is the standard package of RT7243GQW IC. Besides, it contains a set of easy-to-use accessories like house PCB, transformer, capacitors, resistors and diodes, making it convenient for users to easily set up the board and its margin test.

  The working principle of this evaluation board can be simplified as below. Firstly, when the module switch on, the self-start circuit starts work and the EVB_RT7243GQW modular feedback starts operation. The MCU would check the secondary winding voltage and then relates with the load current of main winding. After that, the MCU takes over the control loop to modify inductor current to track Maximum Power Point (MPP). In this way, the power factor and efficiency of power module is maximized. Besides, the MCU also takes over the protection loop to protect the secondary winding against the overvoltage and the over-current.

  EVB_RT7243GQW is especially suitable for isolated DC/DC & AC/DC (Off-Line) SMPS applications at high power levels. The evaluation board offers a variety of features that makes it an ideal platform for circuit design and testing. These features include flexible synchronous rectification, low audible noise and high power factor. Besides, the EVB_RT7243GQW provides advanced protection features, such as overcurrent and overvoltage protection, enabling stable, reliable operation.

  In summary, EVB_RT7243GQW is an evaluation board which designed to evaluate and demonstrate the RT7243GQW IC, and it is an ideal platform for both circuit design and testing, such as ISR in the isolated DC/DC & AC/DC (Off-Line) SMPS applications at high power levels. The working principle and the features of this evaluation board make it a reliable and powerful choice for engineers who want to develop their applications with ease.
