Evaluating the LTC3888/LTC3888-1, 8-Phase, Single Output Synchronous Buck Converter with Power System Management

Overview

TopologyBuck Converter
Input voltage7-14 V
Output 11.8 V / 400 A

Description

Demonstration circuit DC2888A-A/DC2888A-B is an 8-phase single- output, high efficiency, high density, synchronous buck converter with 7 V to 14 V input range. The output can supply up to 400 A maximum load current. The demo board showcases one LTC3888/LTC3888-1 working with eight LTC7051. The LTC3888/ LTC3888-1 is a PMBus-compliant dual loop 8-phase step-down DC/DC controller with digital power system management. LTC7051 is an integrated smart power stage with current sense and temperature monitor. Refer to the LTC3888/LTC3888-1 and LTC7051 data sheets for detailed information.
