ANALOG DEVICES EVAL-LT7171-1-AZ Evaluation Board, LT7171RV-1#TRPBF, Synchronous Buck Regulator

EVAL-LT7171-1-AZ evaluation board has two dual-phase monolithic DC/DC synchronous step-down regulators with a 2.9V to 16V input range featuring LT®7171-1. The output can supply up to 40A continuous load current. The Silent Switcher® structure is incorporated into the LT7171-1 to minimize EMI and reduce PCB layout sensitivity. It also integrates digital power system management functionality, allowing for programmability and telemetry with a PMBus/I2C compliant serial interface. This evaluation board is designed for 1.0V output with a switching frequency set at 1MHz. The controlled on-time valley current-mode control with 25ns typical minimum on-time enables a high switching frequency at a low output voltage with excellent transient response in a small overall solution size. The EVAL-LT7171-1-AZ powers up to default settings and produces power based on the NVM configuration without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter.

• 1V default output voltage
• 1MHZ switching frequency
• 88.2% efficiency at VIN = 12V, IOUT = 20A%
