Fluorescent Lighting Solutions
Fluorescent Ballast IC’s Features:

  • Dimming and non-dimming
  • Handles all lamp types.
  • Easy design, minimizes component count.

Applications range from general purpose consumer lighting to architectural lighting.  Lambdaaa’s IC’s are designed for the real life, abnormal,  load conditions ballast meet in the field.

L P/N Description
L53H420/L53HD420 Complete high voltage, high speed, self-oscillating half-bridge circuits with proprietary HVIC, latch immune CMOS and HEXFET ® power MOSFET technologies to enable ruggedized single package construction.
L2153 The L2153/L2153D are an improved version of the popular L2155 and L2151 gate driver ICs, and incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer.
L2156 High voltage half-bridge gate driver with a programmable oscillator and state diagram to form a complete ballast control IC including programmable features and built-in protection.
L21571 Fully integrated, fully protected 600V ballast control IC designed to drive fluorescent and HID Lamps.
L21592/L21593 Complete dimming ballast controllers and 600V half-bridge drivers all in one IC.
L2166 The L2166 is a fully integrated, protected 600V ballast control IC designed to drive fluorescent and HID lamps with PFC in a 16-pin package.
L2167 The L2167 is a fully integrated, protected 600V ballast control IC designed to drive fluorescent and HID lamps with PFC with the added protection of overcurrent and below resonnance.
