Control IC reduces part count for dimming applications

New Products |
By eeNews Europe

The IRS2983 employs primary side regulation that reduces component count and simplifies design by eliminating the opto-isolator and other components necessary for isolated feedback for fixed loads.

The device also features a rapid startup circuit that reduces the turn on time of the system.

The IRS2983 also offers high power factor and low THD and operates over a wide input range for many LED lighting applications. Comprehensive protection features including hiccup mode over-voltage protection, cycle-by-cycle over-current protection and open and short circuit protection are also included. The device also supports TRIAC dimming.

Other key features of the IRS2983 include critical-conduction mode operation, with discontinuous and burst modes at light load as well as flexibility allowing easy connection opto-isolated feedback circuitry for more complex designs.

Available in an SO-8 package, the IRS2983 utilizes IR’s advanced high-voltage IC process to deliver superior protection from electrical over-stress also offering micro-power startup, low quiescent current, latch immunity and ESD protection and noise immunity.

Availability and Pricing

Pricing for the IRS2983 begins at $0.45 each in quantities of 10,000-units. Production quantities are available immediately. The devices are lead free and RoHS compliant.
