The IRS2980 is the latest addition to IR’s range of Buck controllers complementing  
the existing IRS25401/11 series for non-isolated LED driver applications. The IRS2980  
includes a high voltage regulator which enables the IRS2980 to be supplied directly  
from the input voltage bus and differential high side current sensing enabling the  
use of a single MOSFET and ultra-fast diode as well as maximum frequency limiting.  
These improvements provide design simplification and cost saving while being able  
to operate up to 450V with adequate thermal relief. A PWM dimming interface is also  
incorporated making the IRS2980 a versatile low cost LED driver solution.  
Applications include LED bulb replacement, indoor and outdoor signage as well as  
architectural, entertainment design and decorative lighting.  
The IRS2980 and IRS25401/11 operate in continuous conduction mode using hysteretic  
average current control.
