High Power LED Driver for Lighting

Product Announcement from ROHM Semiconductor USA, LLC

High Power LED Driver for Lighting-Image

The BP5845W isolated LED driver features a constant current output (set via external resistors) and an integrated transformer. This high powered LED is capable of driving 6-9 1W LEDs from 100VAC input. In addition, flicker-free dimming (0-100%) is possible using PWM control.

This product is ideal for LED lighting applications.


  • Wide input voltage range: 80V to 120VAC
  • Offered in a compact, low profile package (46.0 x 22.2 x 18.3mm) ideal for portable sets
  • Built-in transformer reduces the number of external parts required and simplifies power supply configuration
  • Isolated package type
  • Constant current output (set via external resistors)
  • PWM dimming function (0-100%)
