BP58xx Series

High-Efficiency Isolated Driver Modules Optimized for High-Intensity LEDs Now at Digi-Key

ROHM introduces one of the industry’s first isolated AC/DC LED driver modules featuring constant-current circuits optimized for driving LEDs. The new BP58xx series integrates all required LED-driving control circuits, switching elements, isolation transformers and constant-current circuits into a single SIP package. The result is an all-in-one solution that increases power-conversion efficiency in a broad range of illumination/lighting applications including: theater, landscape, residential, commercial and emergency lighting. Constant-current output and adjustable brightness control offer designers a highly accurate, high-performance device for simplifying designs while saving valuable board space.

Key Features

  • Constant-current output optimized for driving LEDs (current set via external resistor)
  • Minimal ambient temperature-based, constant current fluctuation (±1 percent accuracy)
  • High power-conversion efficiency of 85 percent (2 to 8 percent improvement over conventional discrete solution)
  • Isolated AC/DC Circuit
  • Compact SIP11 package (BP5845W: SIP16) with built-in switching transformer
