CCM PFC控制器

The L4984D is a current-mode PFC controller operating with line-modulated fixed-off-time (LM-FOT) control. A proprietary LM-FOT modulator allows fixed-frequency operation for boost PFC converters as long as they are operated in CCM (continuous conduction mode).\n\n The chip comes in a 10-pin SO pack • Line-modulated fixed-off-time (LM-FOT) control of CCM-operated PFC pre-regulators \n• Proprietary LM-FOT modulator for nearly fixed-frequency operation \n• Proprietary multiplier design for minimum THD of AC input current \n• Fast “bi-directional” input voltage feedforward (1/V2correction) \n• Acc;
