Analog Devices Inc. LTC3315B Demo Board (DC2748)

Analog Devices Inc. LTC3315B Demo Board (DC2748) is designed to evaluate the LTC3315B dual 2A monolithic synchronous step-down converters. The LTC3315B converters support adjustable output voltages from 0.5V to VIN. The DC2748A demonstration circuit's operating mode can be selected as burst mode operation, skip mode, or Forced Continuous (FC) mode. This demonstration circuit allows the LTC3315B to sync to a clock frequency range from 3MHz to 10MHz by setting up JP1 to the FC/SYNC position. The LTC3315B converters operate in forced continuous mode when syncing to an external clock.
