  1. Reduce EMI by sweeping a power supply's frequency
    Switching power supplies can be notorious noise generators. You should prevent this noise, which is conducted, radiated, or both, from returning to the input source, where it can potentially wreak havoc on other devices...

  2. Delay Circuitry Controls Supply-Voltage Startup Sequence
    For some ICs, supply voltages should be applied in a particular sequence. One example is the subscriber line interface circuit (SLIC), which, depending on the application, may require several negative and/or positive...

  3. Inverting buck-boost converter regulates LED current
    Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to forward bias the...

  4. Increase Output Voltage With A Voltage Multiplier
    Applications such as printers, laser-based fiber optic systems, and charged-particle air filtration systems require hundreds or even thousands of volts at low power. Flyback converters and autotransformer boosts are...
