The IRS2982S is equipped with a 600 V high-voltage start-up unit that allows the “lighting time†to be less than 0.5 seconds and saves the external partial resistor. The configurable critical conduction mode (CrCM) and discontinuous conduction mode (DCM) ensure that it meets a wide range of application needs and is suitable for dimming LED converter designs in the full current range. The main application of the IRS2982S is an isolated flyback converter in CV (constant voltage) mode. It can also be flexibly applied to non-isolated flyback converters, buck converters, boost converters and SEPIC in CC/CV mode. Other primary top converters, etc.). 
To keep power consumption to a minimum, the IRS2982S supports burst mode (Burst-mode) that ensures ultra-low standby power consumption. The device supports a wide input voltage range from 85 VAC to 305 VAC with overvoltage and overcurrent protection. The optimized single-stage PFC/flyback design ensures a power factor greater than 0.9 and a THD (total harmonic distortion) as low as 20% or less.
Availability
The Infineon IRS2982 has been mass-produced and the 50 W flyback controller evaluation board is available for designers to quickly evaluate and test ICs in LED applications.
