L4984DTR

CCM PFC CONTROLLER

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameSSOP 10

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).The chip comes in a 10-pin SO package...

Key features
  • Line-modulated fixed-off-time (LM-FOT) control of CCM-operated PFC pre-regulators
  • Proprietary LM-FOT modulator for nearly fixed-frequency operation
  • Proprietary multiplier design for minimum THD of AC input current
  • Fast “bi-directional” input voltage feedforward (1/V2correction)
  • Accurate adjustable output overvoltage protection
  • Protection against feedback loop failure (latched shutdown)
  • Inductor saturation protection
  • AC brownout detection
  • Digital leading-edge blanking on current sense
  • Soft-start
  • 1% (at Tj = 25 °C) internal reference voltage
  • - 600 / + 800 mA totem pole gate driver with active pull-down during UVLO and voltage clamp
  • SSOP10 package
