The Power Integrations LYT4328E is a high-power LED driver IC from the LYTSwitch-4 family. It functions as a single-stage, primary-side constant current (CC) controller with power factor correction (PFC).
Key electrical specifications include a 725V breakdown voltage, 78W maximum output power, and a switching frequency of 140kHz. It offers better than ±5% CC regulation and supports TRIAC dimming to less than 5% output. The device achieves high power factor (>0.9) and efficiency up to 92%, while keeping THD below 10% in optimized designs.
Designed for high-line applications, this IC is housed in a 7-SSIP, 6-lead package with through-hole mounting. It features an internal switch and provides isolated output.
The LYT4328E is suitable for various LED driver applications requiring accurate current control and efficient power conversion.
