SN51DP

The is a specialized power management and LED driver integrated circuit (IC) primarily utilized in the backlight inverter circuits of LCD and LED televisions . Manufactured by ON-BRIG , this IC is frequently found in display panels for brands like Hisense, Sony, and Arielli. Technical Specifications and Overview

  • LED forward voltage (V_F): 1.15V typ, 1.4V max @ I_F=10mA
  • Input trigger current (I_FT): 5mA typ, 10mA max – this is the current needed to turn on the output.
  • Turn-on time (t_on): ≤ 0.1ms (zero-crossing delay not included)
  • Zero-crossing voltage threshold: 20V typ (output triggers within ±20V of AC zero)

(some sources list a broader 1.8V to 5.5V range for specific variants). Operating Temperature : Typically -20°C to 130°C Applications sn51dp datasheet verified
