High Performance, Combined Driver, Controller, Switch

The LYTSwitch family enables off-line LED drivers with high

power factor which easily meet international requirements for THD

Figure 1. Typical Schematic.

and harmonics. Output current is tightly regulated with better

than ±±5 CC tolerance¹. Efﬁciency of up to 925 is easily

achieved in typical applications.

TRIAC Dimmable

Supports a Wide Selection of TRIAC Dimmers

The LYTSwitch 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 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 family do not use primary-side

aluminum electrolytic bulk capacitors. This means greatly

extended driver lifetime, especially in bulb and other high

temperature applications.
