IRS2980 - LED Driver Control IC - International Rectifier

Some of the Features - Dimming LED driver controller, Hysteretic Current Regulation, Closed-loop LED current dimming control, Analog/PWM Dimming Input, Internal High Voltage Regulator.

IRPLLED13 - 90-250VAC Offline LED Driver using LEDrivIR IRS2980

Non-isolated constant current buck regulator,  90-250V AC input voltage, 0-50V DC output voltage, Nominal output current of 350mA.

A simple single st age power converter based around the IRS2980 LED driver IC provides a contro lled current output ov er a wide AC line or DC voltage input range.

The IRPLLED13 evaluation board is an off line non-isolated constant current Buck regulator LED driver designed to supply a nominal 350mA DC output current. The LED output voltage can be up to 90% of the input voltage, operating from an AC line input volt age between 90 and 250VAC 50/60Hz. The IRPLLED13 demo board is not de signed for use with dimmers.
