Application Notes

  • Clamshell Phone w/OLED/LCD Screen Using the TPS61140 Dial Output Boost Regulator
    PDF, 49 Kb, File published: Jul 6, 2006
    The TPS61140/1 is a dual output boost converter providing regulated voltage and current output with one boost converter. The reference design and application example shown in this document can be used to power a clamshell phone with an organic light-emitting diode (OLED) and a LCD screen. This device is ideal for driving the OLED sub display and WLED backlight for the LCD main display in clamshell

    PDF, 418 Kb, Revision: A, File published: Dec 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.
