TPS92660 Description
The TPS92660 is a two-output LED driver with 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 the device is a non-synchronous buck controller which is used to regulate current of higher power white LEDs.
