Texas Instruments TPS92660 Two-Output LED Driver

TI TPS92660 Two-Output LED Driver

Texas Instruments TPS92660 Two-Output LED Driver features one time programmable (OTP) ROM and I2C interface for LED current trim. The current trim provides a way for LED fixture manufacturers to produce LED lighting fixtures at a consistent lumen output without binning LEDs. One output of this TI device is a non-synchronous buck controller used to regulate current of higher power white LEDs. The other output of TPS92660 is a linear regulator controller used to regulate current of lower power red LEDs. TPS92660 LED Driver is used for applications of controlled CCT (correlated color temperature) LED lights by mixing white LEDs with red LEDs. This device is available in a 20-pin, TSSOP exposed pad package.
