Analog Devices LT7170-1 | Demoboard EVAL-LT7170-1-AZ

Description

Evaluation kit EVAL-LT7170-1-AZ is a dual-phase single-output monolithic DC/DC synchronous step-down regulator with a 2.9V or 1.5V with EXTVCC to 16V input range featuring LT®7170-1. The output can supply 20A continuous load current. The Silent Switcher® regulator structure is incorporated into the LT7170-1 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. Refer to the LT7170-1 data sheet for more detailed information.
