A high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other non-isolated LED driver applications.First in a family of high-voltage LEDrivIR ICs, and utilizes hysteretic average current mode control for precise current regulation. EOL
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.
