  1. Michael Dunn EDN The name of Dr. Slobodan Ćuk (pronounced, roughly, chook) is familiar to most engineers as the originator of the eponymous Ćuk DC-DC converter architecture, justly famed for its low input output ripple currents, and ability to act ...
  2. Frederik Dostal, Analog Devices Analog Dialogue Question: How can I increase the efficiency of my isolated power supply? Answer: For most step-down regulators, also called buck regulators, it is standard in typical applications to use active ...

  5. Mangjing Xie Electronic Design Isolated dc-dc converters are prone to excessive in-rush current, but a small soft-start circuit can solve the problem and limit that current. Most dc-dc converters require a soft-start circuit to limit the in-rush ...
  6. Lou Frenzel Electronic Design Charge pumps are ideal for designs using a larger, main single-voltage power supply that requires lower-current auxiliary voltage sources, and can handle ICs and components that demand multiple voltages. A charge pump ...
  7. Brian King, Texas Instruments EDN In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through the LED results ...
