Constant Current LED Driver for Illumination

Product Announcement from ROHM Semiconductor USA, LLC

Constant Current LED Driver for Illumination-Image

Developed using energy saving technologies adopted from AC/DC converter designs, the BP5843A constant current LED driver seamlessly integrates all control circuits, switching elements, transformers, and constant current circuits required for LED drive into a compact, isolated SIP form factor.

Features include: wide input voltage range - 113V-170VDC (80V-120VAC); constant current output optimized for driving LEDs; superior power conversion efficiency - 85%; compact SIP11 package with built-in switching transformer reduces the number of external parts; and minimal output current fluctuation (±1%) over a wide range of ambient temperatures.

Ideal for lighting devices in a variety of fields including theatrical, residential, landscape, facility, and disaster prevention.
