The IRPLLED7 evaluation board is an off line non-isolated constant current Buck regulator LED driver designed to supply a 350mA DC output current. The LED output voltage can be up to 90% of the input voltage, operating from an AC line input voltage between 90 and 250VAC 50/60Hz. It also includes PWM dimming capability from 10% to 100% of light output controlled by an on board potentiometer. Read this app note to learn more.
