  • 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
  • Buck Boost vs. Buck Converter Battery Life for Portable 3.3V Micro Hard Disk Drive Applications
    drive voltage of. 3.3V, an obvious dilemma associated with this application is whether to use a low dropout DC/DC step-down. (buck) converter or a step-down/step-up (buck-boost) converter. A buck converter (Figure 1) provides the most efficient solution with the smallest external components
  • Make a White LED Torch Using a Buck Converter
    and where a DC-DC boost or buck-boost converter. was required for a given illumination, you can now place a. DC-DC buck converter.
  • 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
  • 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
  • Step-Up Switching Regulators
    When a low DC voltage source is used to power circuitry operating at high voltage levels, a step-up (boost) converter can be used. The input (lower voltage) is utilized to charge a passive component, such as a capacitor or inductor by the switching action of a transistor(s). Energy is stored
  • Inverting Applications Made Simple
    Designers often require power sources with negative output voltages. There are many different ways to produce a negative output voltage from a positive input voltage. One option is a polarity-inverting buck-boost converter. The advantages of this topology are that it requires low component count
  • TPD12S015 PCB Layout Guidelines
    connectors. This solution is geared toward the smallest possible board area. To meet that goal, the TPD12S015 provides integrated level shifter capabilities from 1.1V - 3.6V (VCCA range) to 5V. Additionally, the device is capable of generating 5V from a 2.3V-5V battery using internal boost converter
