POWER INTEGRATIONS LYT5216D-TL Datasheet & Stock

LYTSwitch™-5 family is ideal for single-stage power factor corrected constant current LED applications like bulbs, tubes and ballasts. It is a single-stage LED Driver IC with combined PFC and constant current output in isolated and non-isolated topologies. 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. EcoSmart™ switching technology ensures maximum efficiency for each device size and load condition.
