LYT5225D-TL
LED DRVR Buck/Buck-Boost/Boost/Flyback/Tapped Buck 1-CH 0.2A 16-Pin SO-B T/R
Avnet Manufacturer Part #:
LYT5225D-TL
RoHS Non-Compliant
LYT5225 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 discontinuous 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 electronically quiet SOURCE pins and frequency jitter ensures extremely low EMI. This reduces the size of the input filter components-greatly reducing audible noise.
