TPS92660参考设计应用电路：

图1TPS92660内部结构图

TheTPS92660 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.

TheTPS92660 is a dual-channel LED current controller. It has a high-voltage, non-synchronous buck controller capable of driving an N-channel high-side MOSFET and a linear controller capable of driving an N-channel lowside MOSFET. The buck controller uses a controlled on-time (COT) control scheme to regulate the LED current.
