TPS92660 - Two-String LED Driver

General 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.
