The current trim provides a way for Overvoltage Protection LED fixture manufacturers to produce LED lighting • Enable On/Off fixtures at a consistent lumen output without binning LEDs. • Accurate 3.0-V Reference Voltage • > 95% Efficiency One output of the device is a non-synchronous buck controller which is used to regulate current of higher • Thermal Shutdown Protection power white LEDs. The other output of the device is a • 20-pin TSSOP Exposed Pad Package linear regulator controller which is used to regulate current of lower power red LEDs. The TPS92660 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.
