XRP7704EVB is an evaluation board from Power Integrations, an American company specialized in the design and development of energy efficient solutions for power conversion. The board was designed to support low-cost, high-efficiency DC/DC or AC/DC SMPS (Switched-Mode Power Supply) applications, such as those found in industrial, automotive, consumer and portable electronic applications.The XRP7704EVB is engineered with a simple and powerful power conversion circuit based on Power Integrations\' topology and ICs. It features a low-cost off-line primary side PFC (Power Factor Correction) controller and a secondary-side synchronous phase shift buck converter. The board\'s primary components consist of High-side MOSFET, Low-side MOSFET, Control IC (LNK6106E, LNK6109E, and LNK6724A) and a Auxiliary IC (CEE1205E), as well as several external components, a bridge rectifier, two electrolytic capacitors and a safety isolation transformer.The board is designed to emulate a several real world power conversion scenarios and thereby allows engineers to investigate and optimize power conversion system parameters such as operating frequency, efficiency, output voltage and response to load changes. The performance specifications of the board is highly adjustable with 11 pin jumpers, allowing for a wide range of application requirements.The board also includes integrated protection features such as adjustable current limiting, short circuit protection, pole synchronous buck converter, over-voltage protection and temperature monitoring.The overall purpose of the XRP7704EVB is to enable engineers to generate a prototype very quickly. This can be used to evaluate applications such as AC-DC switching regulator, DC-DC switching regulator, Power Factor Correction IC and/or System, Low voltage/current DC Power Supply or to verify the response to changes in input voltage, load current, temperature and other parameters.In summary, the XRP7704EVB has an application field that includes industrial, automotive, consumer and portable electronic applications and its working principle is based on a low-cost off-line primary side PFC controller and a secondary-side synchronous phase shift buck converter. It features adjustable performance, integrated protection features and enables engineers to generate a prototype quickly.
