The LYT7504D is part of the LYTSwitch-7 family of LED driver ICs designed for single-stage, high power factor, constant current applications. It operates in critical conduction mode (CrM) and is suitable for dimmable LED applications with a power range of 4 W to 22 W. The device features a robust 725 V MOSFET, ensuring high line voltage surge resistance and low turn-on losses, which allows for the use of slower reverse-recovery output diodes. This LED driver provides ±3% constant current regulation and achieves a power factor greater than 0.9 with efficiency exceeding 85%. It supports a wide input voltage range of 90 VAC to 308 VAC and offers a dimming ratio better than 10:1 with a fast turn-on time of less than 500 ms. The LYT7504D includes comprehensive protection features such as input and output overvoltage protection, thermal foldback, and output short-circuit protection, enhancing reliability in various operating conditions. The device is packaged in a compact SO-8 form factor, making it suitable for applications where space is a constraint. Its low component count simplifies design and reduces overall system costs, making it an attractive option for engineers looking to implement efficient LED driver solutions.
