Analog Devices Inc. DC1898A Demo Board is a triple output synchronous step-up/dual step-down supply featuring the LTC3899EFE DC/DC controller. This board includes rail tracking (buck channels only), an internal 5V linear regulator for bias, and a separate RUN pins for each output. The DC1898A board features DRVSET jumper to set the gate driver voltage, a mode selector to run in CCM, and pulse skip or Burst Mode® operation. This board operates at 2.5V to 60V input voltage range and 5V to 10V output voltage range. The resultant wide input voltage ranges make the board suitable for automotive or other battery fed applications.
