EVAL-LT7176-AZ

EVAL-LT7176-AZ is a dual-phase single-output monolithic DC/DC synchronous step-down regulator evaluation board with a 2.7 to 4V input range featuring LT®7176. With 3 to 12V EXTVCC provided, the input voltage can be as low as 1.5V. The output can supply 48A continuous load current. The Silent Switcher® regulator structure is incorporated into the LT7176 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. The board is designed for 0.5V output with a switching frequency set at 1.5MHz. 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 board powers up to default settings and produces power based on the NVM configuration without the need for any serial bus communication.

• 48A typ maximum continuous output current
• 76% typ efficiency at VIN = 3.3V, IOUT = 40A
