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.
