ADI’s Silent Switcher® Technology

Industry’s highest efficiency, lowest noise switch mode power supply

Silent Switcher regulators and smart power stages provide new levels of performance for synchronous DC-to-DC converters. Featuring ADI’s proprietary technology, Silent Switcher devices provide industry’s best combination of high efficiency (up to 96%), low noise, ultralow EMI and smallest footprint, easily passing the CISPR 25 Class 5 peak EMI limits. With support for input voltages as high as 65V, load currents up to 30A, and high step-down ratios due to low minimum on times, there’s a Silent Switcher solution suitable for most applications including industrial, instrumentation and measurement, healthcare, aerospace, communications, automotive and more.

Features

  • Ultralow EMI emissions (SS1, SS2, SS3)
  • High Efficiency at High Switching Frequency (SS1, SS2, SS3)
  • Integrated capacitors for smaller solution size and even lower EMI (SS2, SS3)
  • Eliminate PCB layout sensitivity to achieve excellent EMI performance (SS2, SS3)
  • Ultralow Low Freq Noise (SS3)
  • Ultrafast Transient Response (SS3)
  • Replace LDOs and directly drive with Silent Switcher 3
