PT4531

TRIAC Dimmable LED Driver

GENERAL DESCRIPTION

FEATURES

The PT4531 is a current mode PFM AC/DC boost

converter with integrated 700V MOSFET. The

device can keep output current constant by setting

an external resistor. It can provide up to 15W

output, and is ideal for all kinds of LED lighting

applications.

PT4531 can be powered by the AC mains directly,

and it can keep the output current constant even

when the input voltage fluctuates in a large range.

PT4531 is available in a ESOP-8 package.
