Notas de aplicación

  • TPS61150 Dual Output Boost Converter Drive Up to 14 WLED Keypad LCD Backlight
    PDF, 70 Kb, Archivo publicado: jul 5, 2006
    The TPS61150/1 is a high-frequency boost converter with two regulated current outputs for driving white light-emitting diodes (WLED). The reference design and applications examples in this document show the TPS61150 driving up to 14 WLEDs, a keypad, and a LCD backlight application. The two current outputs are ideal for driving WLED backlight for the sub and main displays in clamshell phones.
  • Analog PWM Dimming in White-LED Drivers
    PDF, 539 Kb, Archivo publicado: dic 21, 2016
    Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LEDdriver devices. PWM dimming takes a rectangle waveform with variable positive duty cycle (D) and adjuststhe LED current proportionally. For many smaller format white LED drivers (7-inch screen size or smaller),the PWM signal is converted to a DC control voltage and made to drive the LED current in
  • Minimizing Ringing at the Switch Node of a Boost Converter
    PDF, 201 Kb, Archivo publicado: sept 15, 2006
    The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter.

  • 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.
