Adjustable output voltage: 200-W SEPIC power supply reference design


This 200-W SEPIC converter reference design supplies a non-isolated adjustable 5-V to 200-V output voltage with a maximum output current of 4 A. Output voltage is set using a 0% to 100% duty-cycle: pulse-width-modulation (PWM) input.

  • Provides 3x to 5x higher output power than traditional SEPICsAchieves a peak efficiency of greater than 93% (at 100-V output: 200 W)Controls the output voltage with PWM input from processorEnables low-input-ripple voltage and low EMI compared to flyback converters
