UCC28019EVM

Оценочный модуль для PFC контроллера UCC28019 с режимом постоянной проводимости.

The UCC28019EVM is an evaluation module for UCC28019, a 350W off line power factor correction (PFC) controller uses the boost topology operating in continuous conduction mode (CCM). The controller is suitable for systems in the 100W to 2kW range over a wide range universal AC line input. Startup current during under voltage lockout is less than 200µA. The user can control low power standby mode by pulling the VSENSE pin below 0.77V. Low distortion wave shaping of the input current using average current mode control is achieved without input line sensing, reducing the component count. Simple external current and voltage loop compensation, along with advanced protection features, make this controller ideal for server and desktop power supplies, telecom rectifiers, and home electronics.
