45 V Two-Terminal LED Drivers

onsemi and Digi-Key introduce new constant current regulators

Image of onsemi 45V Two-Terminal LED DriversThese two-terminal linear constant-current regulators from onsemi are simple, economical and robust devices designed to provide a cost effective solution for regulating current in LEDs. Based on patent pending self-biased transistor technology, the drivers regulate output current over a wide range of input voltages. They are designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and operating temperatures. The devices require no external components and their high anode-cathode voltage rating withstands surges common in automotive, industrial and commercial signage applications. They are lead-free ROHS compliant, use halogen-free molding compound and are qualified to stringent AEC 101 standards.

Features
  • Regulated current enables:
    • Constant brightness over wide voltage range
    • Protection of LEDs from over drive at higher input voltages
    • Brighter LEDs at lower voltages
    • Reduced or eliminated LED binning inventory
    • Lower overall solution cost
  • 45 V max operating voltage withstands battery load dump
  • Power packages (SOD123/SOT223) operate in harsh thermal environments (85°C still air)
  • Negative temperature coefficient protects devices and LEDs
Applications
  • Commercial signage
    • Neon replacement
    • Transportation signs
    • Display backlighting
  • Architecture and general lighting
    • Flat panel AC lighting
    • Task and decorative lighting
    • Landscape and exterior lighting
  • Automotive
    • Interior lighting
    • Stop/tail light
    • CHMSL
    • Cluster and convenience
