GP8675E

GP8675X is a constant voltage, constant current primary-side feedback valley-switching control IC designed for chargers and adapters. The IC employs a proprietary output cable loss compensation technique to effectively compensate for the voltage drop caused by output current across the output cable. With a built-in loop compensation circuit, no external compensation components are required, ensuring excellent system stability. The GP8675X achieves superior CV/CC characteristics and meets standby power consumption requirements of less than 75mW. The IC features multiple protection functions, including open-circuit protection, overvoltage protection, and short-circuit protection, and is available in an SOP8 package.
