Notas de aplicación

  • 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
  • Improved Overvoltage Protection for the TPS61040/1
    PDF, 78 Kb, Archivo publicado: marzo 15, 2006
    This application report presents an improved overvoltage protection circuit using a Zener diode for the TPS61040/1.
  • 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
  • TPS61042 Dual Li-Ion and Higher Input Voltages
    PDF, 46 Kb, Archivo publicado: marzo 13, 2003
    This document shows how to operate the TPS61042 from input voltages greater than 6 V. The ability to operate from input voltages greater than 6 V allows the TPS61042 to operate from dual Li-Ion or higher input voltages.
  • TPS61040 Inverter Design (Rev. A)
    PDF, 56 Kb, Revisión: A, Archivo publicado: jun 9, 2003
    Although designed to be a positive voltage boost converter, the TPS61040 can be configured as an inverting converter using an OPA348 operational amplifier or equivalent to invert the feedback signal.
  • High Voltage Power Supply Using the TPS61040
    PDF, 32 Kb, Archivo publicado: jul 9, 2002
    The TPS61040 is a highly integrated, low power, boost converter capable of delivering output voltages up to 28 V. The addition of two small diodes and two small capacitors enables the TPS61040 to deliver output voltages up to 50 V.

  • 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.
