应用须知

  • Clamshell Phone w/OLED/LCD Screen Using the TPS61140 Dial Output Boost Regulator
    PDF, 49 Kb, 档案已发布: 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
