Infineon Unveils multimode flyback controller specifically for mid- to high-end LED Lighting Designs

IC for LED

Infineon Technologies launches a multimode flyback controller IC for LED applications which is known to mitigate ‘time-to-light’, lower component counts and reduce operational and standby power consumption.

Designed to meet the performance and efficiency demands of mid-range to high-end LED designs, the IRS2982S provides a versatile controller solution that can meet the needs of a wide variety of interior, outdoor, office and industrial lighting schemes.

Eminent Features:

  • The IRS2982S incorporates a 600 V high-voltage start-up cell that delivers a fast ‘time-to-light’ of less than 0.5 s. At the same time, it eliminates the need for external components for voltage division.
  • Configurable Critical Conduction Mode (CrCM) and Discontinuous Current Mode (DCM) operation ensure compatibility with a wide range of application requirements making the device suitable for dimming LED converter designs across the full current range.
  • The key application of the IRS2982S is the isolated flyback with CV (constant voltage) mode which opens up design flexibility in other topologies, such as non-isolated flyback with CC/CV, buck, boost, and SEPIC (single ended primary inductor converter).
  • With minimum power consumption, the IRS2982S features a burst mode capability that ensures ultra-low standby power.
  • The device operates from a wide input voltage range of 85 VAC to 305 VAC and incorporates over-voltage and over-current protection as standard.
  • An optimized single-stage PFC/flyback design ensures a power factor of higher than 0.9 and a low THD of below 20 percent.


Volume production of the Infineon IRS2982S is already underway and a 50 W flyback evaluation board is available for designers looking to rapidly evaluate and test the IC in their LED applications.
