Analog Devices LT7184S | Demoboard EVAL-LT7184S-AZ

Beschreibung

The EVAL-LT7184S-AZ evaluation board is a dual-output PolyPhase® monolithic DC/DC synchronous step-down regulator with a 2.9V or 1.5V with EXTVCC to 16V input range featuring LT®7184S. Each output can supply -8A to +9A continuous current and simultaneously deliver up to 7A of continuous current from both channels. The second-generation Silent Switcher® regulator structure is incorporated into the LT7184S to minimize EMI and reduce Printed circuit board (PCB) layout sensitivity. It also integrates digital power system management functions, allowing for programmability and telemetry with a PMBus/I2C-compliant serial interface. Refer to the LT®7184S datasheet for more detailed information.
