反激式转换器的过渡模式PFC控制器

The HVLED007 is a current-mode PFC controller specific for isolated high power factor, flyback converters operated in transition mode (aka quasi-resonant operation). Targeting both indoor and outdoor solid-state lighting applications, it provides extended temperature range operation down to -40 °C w • Transition-mode (quasi-resonant) control of flyback PFC pre-regulators \n• Proprietary input current shaper for minimum THD of line current \n• Control input for isolated feedback and optocoupler driving \n• Output overvoltage protection \n• Overload and short-circuit protection \n• Low (≤ 60 μA) ;
