TPS92612 Single-Channel Linear LED Driver
Texas Instruments' 40 V, 150 mA LED driver is a constant-current source with protection
Texas Instruments' TPS92612 is a single-channel high-side linear LED driver operating from a wide range supply. It is a simple, elegant solution to deliver constant current for a single LED string. The driver can support off-board LED connections with long cables. The TPS92612 device can be used as a general constant-current source or current limiter in other applications. 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.
