EVM3805-QB-25-01A is an evaluation board with a DC/DC and AC/DC (Off-Line) SMPS, which is designed to help evaluate off-line topologies including flyback, forward, and quasi-resonant. The board is based on Intersil’s ISL32152 and ISL32101 combo.The board integrates all the necessary components to construct a complete non-isolated switch-mode power supply (SMPS). Its purpose is to provide a system of practical electrical power conversion that would be easy to develop and optimize for a variety of applications. This evaluation board can be used for a wide variety of applications such as automotive, industrial, medical, consumer, and more.The application field of EVM3805-QB-25-01A is mainly divided into 12V application and 5V application. The 12V application includes devices such as computer power supplies, monitor power supplies, LED lighting, and more. The 5V application includes a wide range of devices such as DVD players, servers, video game consoles, and more. The board is well suited for both 12V and 5V applications due to the customized design that incorporates active compensation and optimized feedback network. The working principle of EVM3805-QB-25-01A can be divided into two main parts: the power stage and control stage. The power stage is responsible for the actual generation of the output voltage and power conversion. It is composed of an isolated transformer, a MOSFET, and a diode. By controlling the turn-on and turn-off of the MOSFET during each cycle, the transformer and the diode are able to convert the AC input into the DC output.The control stage is responsible for the control of the power stage. It is composed of a controller, an optically-isolated feedback, opto-coupler, etc. The controller is responsible for the control of the power stage. It uses the feedback signal from the opto-coupler to adjust the duty cycle and generate the proper output voltage.EVM3805-QB-25-01A evaluation board is a highly efficient power conversion tool that can be used for a wide range of applications. It is designed to provide a low-cost and effective solution for anyone who is looking for a low power off-line SMPS. The board is well suited for both 12V and 5V applications due to the customized design that incorporates active compensation and optimized feedback network. The board’s integrated components make it straightforward to start developing and optimizing power conversion circuits. The EVM3805-QB-25-01A helps engineers to quickly and easily evaluate different topologies and configure the system for specific applications.
