Extending Battery Life with the TPS61040 White Light LED Driver
PDF, 64 Kb, Archivo publicado: mayo 3, 2002
This application note describes how to extend the battery life of a circuit that uses Texas Instrument's TPS61040 low power dc-dc boost converter for driving white light LEDs. Power loss in the current sense resistor is discussed, and a method for reducing this loss is presented. Design equations are given for calculating the proper resistor values for a white light LED driver that includes prov

Using the TPS61040 in High Voltage Applications
PDF, 69 Kb, Archivo publicado: mayo 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.

White Light LED Driver With Gradual Dimming (Rev. A)
PDF, 177 Kb, Revisión: A, Archivo publicado: enero 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 Driver
PDF, 69 Kb, Archivo publicado: 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

Performing Accurate PFM Mode Efficiency Measurements (Rev. A)
PDF, 418 Kb, Revisión: A, Archivo publicado: dic 11, 2018
When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
