Product Brief
Multimode Flyback Controller for LED
IRS2982S
Infineon’s latest Multimode Flyback Controller IC for LED lighting is targeting mid-range
to high-end LED drivers for outdoor, interior, office and industrial lighting applications. Its
integrated startup cell together with CrCM, DCM and burst mode optimize overall efficiency from standby to 100 percent while keeping time to light less than 0.5 seconds and
reducing the use of external components.
Key features
››High voltage startup cell (600 V)
››CrCM/DCM operation
››Burst mode capability
››Accurate constant voltage/current
regulation
The benefits of the high voltage startup cell are:
››Fast time to light < 0.5 s while maintaining > 90 percent efficiency
››Eliminate external components for voltage dividing
››CrCM/DCM/Burst modes enables wide range operation from standby to 100 percent
››Key application is isolated flyback with CV mode and also capable of non–isolated
flyback with CC/CV mode
››Optimized one stage PFC + flyback
››Cycle-by-cycle over-current
protection
››Open load over-voltage protection

Product Brief
Multimode Flyback Controller for LED
IRS2982S
The IRS2982S is ideal for single stage converters with an
unsmoothed DC bus to obtain high power factor and low line
current total harmonic distortion (THD). It supports universal
input and operates both at AC and DC inputs. And lastly, it also
has over voltage and over current protection features.
