DC1667A - LTC3600EDD Demo Board I 4.5V to 15V Input, Adjustable Output with 1.5A IOUT

Demonstration circuit DC1667A is a step-down DC/DC converter using LTC®3600 monolithic synchronous buck regulator. DC1667A has an input voltage range of 4.5V to 15V, and is capable of delivering up to 1.5A of output current. The output voltage of the DC1667 can be set by a single resistor from 0V to (VIN – 0.5)V. At light load conditions, DC1667 can operate in discontinuous mode to improve the efficiency.
