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.
