Silent Switcher®

ADI’s Silent Switcher regulators bring new levels of performance for synchronous step down dc to dc converters. Combining 2MHz switching, high efficiency and ultra-low EMI, they offer very compact and low EMI power solutions.

Maximum input voltages range from 8 V to 65 V making them ideal for a wide range of applications that require 1A to 15 A of output current, including:

  • Automotive
  • Industrial
  • Communications systems

The Silent Switcher family uses special design and packaging techniques to offer 95% efficiency at 2MHz while easily passing the CISPR 25 Class 5 Peak EMI limits. Silent Switcher 2 adds internal bypass capacitors and an integrated substrate to further improve EMI which is not sensitive to PCB layout, simplifying designs and reducing performance risks even when using two-layer PC boards.

chip-LT8650SThe LT8650S combines high efficiency at high frequencies and an ultralow EMI design to deliver a very compact dual output 4A (6A peak) synchronous step-down solution. It delivers efficiency as high as 94.4% (12VIN to 5VOUT) with a switching frequency of 2MHz offering a very compact solution footprint. The LT8650S’s unique Silent Switcher®2 architecture uses four internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the hot loops.
