  • Buck-Boost LED Driver Using the PIC16F785 MCU
    This application note presents the design equations, schematics and source code for a 5.5W power LED driver using the PIC16F785 MCU. The application, as shown, can be connected to operate as a buck-boost converter or a boost converter. The PIC16F785 makes a great choice for this application because
  • Connecting LEDs: Serial vs. Parallel
    converter to create voltages higher and lower than the battery, depending on the state of charge. Connecting all LEDs in series requires a boost converter to create a voltage higher than the power source. In practice, series connected LEDs are powered from DC/DC inductive boost converters, whereas
  • The Evolution of Switched Capacitor Backlight Drivers in Mobile Phones
    of drivers used for LED backlighting: inductive boost converters or charge pumps. To ensure equal brightness of each LED, designers either put all LEDs in series and drive them with a constant current boost converter, or use a switched capacitor charge pump with individual current control for each
  • Generating High Voltage Using the PIC16C781/782
    displays and LCDs. However, for this technical brief, the Nixie tube serves as an excellent visual feedback of the PIC16C782 device's ability to generate high voltage from a low-voltage source. This technical brief introduces the boost converter topology operating in Discontinuous mode. As an example
  • Design Considerations for a Natural User Interface (NUI)
    Recent revolutionary advancements have shown that a more intuitive, engaging and captivating user interface will not only improve the effectiveness of the system, but also boost the productivity of users. As a result, the goal is now a natural user interface (NUI) for applications. Today's
