  • Double Your Output Current With Parallel Voltage Regulators

    By Wayne Rewinkel, December 08, 2004

    To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach uses sense resistors in...

  • Double Your Output Current With Parallel Voltage Regulators (Part 2)

    By Wayne Rewinkel, December 08, 2004

    Example 4: This paralleling technique using the sensing circuit as shown in Figure 5 has been demonstrated with a dual-phase, voltage-mode controller (LM2647) to combine 30-A, 1.2-V channels into a single 60-A output without introducing added loss....
