- White Light LED Driver With Gradual Dimming (Rev. A)PDF, 177 Kb, Revision: A, File published: Jan 10, 2007
Many consumer products using white light LEDs for illumination and backlighting provide gradual LED illumination at turnon and turnoff. This gradual illumination is usually achieved with the aid of a microprocessor that provides PWM dimming control. This circuit uses the Texas Instruments TPS61040 white light LED driver to provide gradual illumination at turnon and turnoff without the use of a mic - Single Cell TPS61041 LED DriverPDF, 69 Kb, File published: Jun 9, 2003
This application report shows how to operate the TPS61041 in a constant current LED drive configuration from input voltages less than 1.8 V. Although most applications using this device connect the VIN pin to the boost inductor, L1, as shown in Figure 1, this is not required. Separating the power stage from the control IC, allows the use of input voltages that are both above or below the operating - Using the TPS61040 in High Voltage ApplicationsPDF, 69 Kb, File published: May 16, 2005
The TPS61040 is a highly integrated, low-power, boost converter capable of delivering output voltages up to 28 V with input voltages up to 6 V. However, using an external transistor in a cascode configuration enables the TPS61040 to be used in applications where higher input or output voltages are required. Output voltages in the 100s of volts are achievable using this technique. - Coupled inductors broaden DC/DC converter usagePDF, 140 Kb, File published: Aug 11, 2010
