Analog Devices Inc. DC3123A Demonstration Circuit

Analog Devices Inc. DC3123A Demonstration Circuit features the LTC3315A dual 5V, 2A synchronous step-down DC/DC regulators operating at 2MHz. One regulator provides a 1.2V output and the other provides 1.8V, both up to a 2A load. The LTC3315A regulator supports adjustable output voltages from 0.5V to V_IN and operating frequencies from 1MHz up to 3MHz. The operating mode of the DC3123A demonstration circuit can be selected as Burst Mode operation, Skip mode, or Forced Continuous (FC) mode. Setting JP1 to the FC/SYNC position will allow the LTC3315A regulator to sync to a clock frequency from 1MHz to 3MHz. The LTC3315A regulator operates in Forced Continuous (FC) mode when syncing to an external clock.
