With LEDs being widely used as a light source, simple LED drivers are more and more popular. Compared to discrete solutions, a low-cost monolithic solution lowers system-level component counts and significantly improves current accuracy and reliability.

The TPS92612 device is a single-channel high-side linear LED driver operating from a wide range supply. It is a simple, yet elegant solution to deliver constant current for a single LED string. It can support off-board LED connection with long cables. The TPS92612 device can also be used as a general constant current source or current limiter in other applications.
