Analog Devices Inc. DC2747A Demo Circuit
Analog Devices Inc. DC2747A Demo Circuit is designed to evaluate the performance of the LTC3315A synchronous step-down converters. This demo circuit can operate in Burst Mode and skip mode or Forced Continuous (FC) mode. The LTC3315A step-down converter supports adjustable output voltages from 0.5V to VIN and operating frequencies from 1MHz up to 3MHz. This step-down converter operates in FC mode when syncing to an external clock. The DC2747A demo circuit operates within 2.25V to 5.5V input supply range. Setting JP1 to the FC/SYNC position will allow the LTC3315A to sync to a clock frequency from 1MHz to 3MHz.
