55 Vin, Low Noise Synchronous Buck Converter Reference Design with 6V, 7A Output


Design files


PMP10898 was designed to power a high frequency radio transmitter with up to 7 A off 6 V powered from "Telecom 48V".  This application needs both low noise and excellent dynamic response when load is switched from near zero to full. Also it needs satisfactory thermal performance for outdoors operation with wide temperature range and no fan. Test Report documents performance in all 3 areas.

  • Low output ripple & well damped main switching node for noise sensitive applications such as high frequency radio
  • Tested at full load with no fan
  • Tested with step load from near no load to full load
  • Ultra-stable design: 75 degrees of Phase Margin & 20 dB gain margin
  • This circuit design is tested and includes a full test report, schematic, and gerber files
