Description
The LYTSwitch™-5 family is ideal for single-stage power
factor
corrected constant current LED applications – bulbs, tubes and
ballasts.
Each device incorporates a high-voltage power MOSFET and discon-
tinuous mode, variable frequency, variable on-time controller. The
controller also provides fast (cycle-by-cycle) current limit, input and
output OVP, plus advanced thermal management circuitry.
The combination of a low-side switching topology, cooling via electroni-
cally quiet SOURCE pins and frequency jitter ensures extremely low EMI.
This reduces the size of the input filter components – greatly reducing
audible noise.
The part numbers shown in Table 1 describe 3 different power levels and
two MOSFET voltage options to cost-optimize designs, while EcoSmart™
switching technology ensures maximum efficiency for each device size
and load condition.
