DC2113A - LTC3649 Demo Board | Sync Buck, 3.1V ≤ VIN ≤ 60V, Vout = 3.3V/5V @ 4A
Demonstration circuit 2113A is a high input voltage, high efficiency synchronous monolithic buck converter featuring the LTC®3649. The DC2113A has wide input voltage range from 3.1V up to 60V. The output voltage of the DC2113A can be set as to 3.3V or 5V. However, “USER SELECT” option of DC2113A allows output voltage to be as high as input voltage minus 0.5V, with certain modifications. DC2113A is capable of delivering up to 4A of output current. DC2113A supports three operation modes: Fixed-Frequency modulation, Burst Mode® operation and the user can synchronize it with external clock also. Fixed-Frequency mode of operation maximizes the output current, reduces output voltage ripple, and yields a low noise switching spectrum. Burst Mode operation employs a variable frequency switching algorithm that minimizes the no-load input quiescent current and improves efficiency at light loads.
