Description

  • DC059A-A, Demonstration Circuit is a step-down (buck) regulator using the high voltage LTC1174-5. Exclusive use of surface mount components results in a highly efficient application in a small board space. This demo board highlights the simplicity of the LTC1174 in stepping down input voltages ranging between 4 to 16.5V. The LTC1174 is a current mode DC/DC converter, thus the peak inductor current is well-defined and provides excellent transient response. To optimize efficiency, the LTC1174 automatically switches between continuous and Burst Mode operation
