The TPS61181 is an ideal LED driver IC for medium form factor LCD backlighting. This device has a built-in, high-efficiency boost regulator with integrated 1.5-A/40-V power MOSFET. It provides six, current-sink regulators of 25 mA. The device can support up to 60 white LEDs. In addition, the boost output automatically adjusts its voltage to total LEDs forward voltage to optimize the whole solution - Extending the Input Voltage Range of the TPS6116x/8x/9x WLED DriversPDF, 124 Kb, 档案已发布: Aug 12, 2009
The TPS6116x, TPS6118x and TPS6119x WLED driver and TPS6117x boost converter integrated circuits (IC) can operate with different input voltages, one powering the IC itself and the other powering the boost power stage. This application report explains various options on how to use the WLED drivers with split power rails. This allows these LED drivers to be used in applications where the available - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev.
