高压启动过渡模式PFC

The L6564H is a current-mode PFC controller operating in transition mode (TM) which embeds the same features existing in the L6564 with the addition of a high voltage startup source. These functions make the IC especially suitable for applications that must be compliant with energy saving regulation • Onboard 700 V startup source \n• Fast “bi-directional” input voltage feedforward (1/V2correction) \n• Accurate adjustable output overvoltage protection \n• Protection against feedback loop disconnection (latched shutdown) \n• Inductor saturation protection \n• AC brownout detection• Low (≤ 100 μA);
