Key Document


This reference design shows an alternative way for a non-isolated PLC power supply to generate a stable output voltage, which is in between the minimum and maximum input voltage. Although a buck boost topology is more commonly used, the coupled inductor single-ended primary-inductance converter (commonly referred as SEPIC) is much more effective and reduces cost.

  • Up to 4W power
  • Up to 91% efficiency
  • Wide VIN from 8V to 36V
  • Precise output voltage of 24V
  • Small form factor
