26-06-2019 | Analog Devices | Design & Manufacture

Analog Devices by Linear Technology DC1898A Demo Board is a triple output synchronous step-up/dual step-down supply highlighting the LTC3899EFE DC-DC controller. This board comprises rail tracking (buck channels only), an internal 5V linear regulator for bias, and a separate RUN pins for every output. The board offers a DRVSET jumper to establish 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 span and 5V to 10V output voltage range.

The resultant broad input voltage ranges make the board ideal for automotive or other battery fed applications.
