Renesas Electronics Corporation LED Drivers ISL1902FAZ-T7A

The ISL1902FAZ-T7A is a high-performance LED driver designed for AC mains applications, featuring excellent current regulation across varying line, load, and temperature conditions. It supports 0-100% dimming through both leading-edge and trailing-edge dimmers, as well as analog control signals, making it versatile for different lighting applications. The driver operates in critical conduction mode (CrCM), which enhances efficiency by allowing near zero-voltage switching and maximizing magnetic core utilization. This LED driver is equipped with power factor correction (PFC) capabilities, achieving a power factor of up to 0.995 and minimizing harmonic distortion. It includes features such as input and output overvoltage protection, over-temperature protection, and bias supply under-voltage lockout, ensuring reliable operation. The device is suitable for various topologies, including Boost, SEPIC, Flyback, and Forward converters, and is compliant with RoHS standards. Its operational temperature range is from -40°C to +125°C, making it suitable for a wide range of industrial and commercial lighting applications.
