Isolated DC-DC SoC

Isolated DC-DC SoC products combine DC-DC controllers with integrated high-voltage isolation. The AS1454/44/34/24 and AS1431/51 are Quad/Single-Output digital power SoCs for 9.5-72VDC & 24VAC isolated power applications.  All are built on Kinetic Technologies’ integrated 2kV digital isolation technology which eliminates the need for opto-couplers or other signal isolation devices.  The combination of DC-DC controller and digital isolation creates a highly flexible power platform which minimizes component count and design footprint.

Synchronous converters with digital loop and timing control are integrated with digital isolation as part of an advance power system architecture for high-efficiency and cost-effective designs.  Selectable spread-spectrum clocking on all PWMs reduces the power supply spectral noise for superior EMC performance.  Bi-directional isolated GPIO and isolated ADC ease system level design in many industrial, telecom, and medical applications.
