SSL21082T - Brand New NXP Semiconductors LED Drivers
-
Description
The SSL21082T is a high-voltage Integrated Circuit (IC) designed for driving LED lamps in general lighting applications. It is part of the LED Drivers product category. The IC is capable of driving strings of LEDs from a rectified mains supply and offers high-efficiency switch mode buck driver options. With integrated 300 V power switches, the SSL21082T provides a power-efficient boundary conduction mode of operation with features such as zero current switching and minimal required inductance value and size. The IC also supports direct PWM dimming and ensures fast transient response through cycle-by-cycle current control. It offers various internal protections, low component count, and easy compatibility with wall switches. The lifetime of the IC matches or surpasses the lifetime of LED lamps.
