Features

  • Converter can step up and down the input voltage
  • Cost-effective topology that uses only two semiconductor devices in the power stage
  • Due to continuous input current SEPIC topology and high switching frequency of 2 MHz, low conducted emissions are achieved which is above AM broadcast band
  • The switching high frequency of 2 MHz enables a smaller physical form factor of the circuit
