MOSFETs - Single

isolated power driverfull bridgetransformer driverspread spectrumSOT-23-5non-regulated isolated supply

CMP6503S is a 3.0 V to 5.5 V full-bridge transformer driver for compact, non-regulated isolated power rails. It integrates power MOSFETs, selectable spread-spectrum switching, current limiting, and thermal shutdown.

Best for

  • Compact non-regulated isolated auxiliary supplies
  • Isolated communication interfaces
  • Isolated low-power analog interface rails

Avoid if

  • Applications requiring tightly regulated output voltage without downstream regulation
  • Designs requiring undocumented compliance or lifecycle status

Check before use

  • Use a transformer specified for the intended input and isolated output
  • Place at least a 1 µF capacitor close to VDD and GND
  • Verify output voltage across the full input-voltage and load range
  • Confirm creepage, clearance, and insulation requirements at PCB level
