HXD-LP5581 is a DC-DC constant-current LED backlight driver specifically designed for 42- to 60-inch professional LCD LED backlight modules. It is highly recommended for smart digital bus shelters, airport/railway flight info displays, large clinical displays, interactive boardroom screens, and factory-floor HMI displays.
80~140 (VDC)
HXD-LP5581 is a high-performance LED constant current driver board designed specifically for large-size LCD backlight driver systems ranging from 42- to 60-inch. Featuring advanced DC-DC boost technology, the backlight driver board converts 24V DC input into a stable 80V-140V LED output, making it ideal for industrial displays, digital signage, medical equipment, transportation systems, and high-brightness LCD display applications. Designed for long-term reliability, HXD-LP5581 offers high efficiency, low thermal dissipation, and stable constant-current operation for demanding industrial environments.
♦ 24V Industrial Power Alignment: HXD-LP5581 works with native industrial 24V (23.5V~25V) DC systems.
♦ 80V-140V High-Voltage Output: Specifically engineered for large panels where multiple LED bars are arranged in long series.
♦ Triple-Output Socket Architecture (6P/13P/4P) for Cross-Brand Compatibility: our PCB board integrates CN2 (6P), CN3 (13P), and CN4 (4P) terminals simultaneously.
♦ DC Dimming: Employs a robust 0V to 5V analog dimming voltage scale 0V= Maximum brightness, 5V=Minimum brightness to output a steady, continuous DC wave.
