Product Details

Product Highlights

  • Better than ±5% Constant Current (CC) Regulation
  • Power Factor Correction (PFC) for Low-Line Applications
  • TRIAC Dimming and Non-Dimming Options

Description

High Performance, Combined Driver, Controller, Switch

The LYTSwitch-4 family enables off-line LED drivers with high power factor which easily meet international requirements for THD and harmonics. Output current is tightly regulated with better than ±5% CC tolerance1. Efficiency of up to 92% is easily achieved in typical applications.

Supports a Wide Selection of TRIAC Dimmers

The LYTSwitch-4 family provides excellent turn-on characteristics for leading-edge and trailing-edge TRIAC dimming applications. This results in drivers with a wide dimming range and fast start-up, even when turning-on from a low conduction angle. Large dimming ratio and low "pop-on" current.

Low Solution Cost and Long Lifetime

LYTSwitch-4 ICs are highly integrated and employ a primary-side control technique that eliminates the optoisolator and reduces component count. This allows the use of low-cost single-sided printed circuit boards. Combining PFC and CC functions into a single-stage also helps reduce cost and increase efficiency. The 132 kHz switching frequency permits the use of small, low-cost magnetics.

LED drivers using the LYTSwitch-4 family do not use primary-side aluminum electrolytic bulk capacitors. This means greatly extended driver lifetime, especially in bulb and other high temperature applications.

Other Features

  • Fast start-up
    • <250 ms at full brightness
    • <1s at 10% brightness
  • High power factor >0.9
  • Easily meets EN61000-3-2
    • Less than 10% THD in optimized designs
  • Up to 92% efficient
  • 132 kHz switching frequency for small magnetics
