产品详情
The EVAL-LT7176P-1-AZ evaluation kit is a dual-phase single-output monolithic DC/DC synchronous step-down regulator with a 2.7V to 4V input range featuring the LT7176P-1. With 3V 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 LT7176P-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 LT7176P-1 data sheet for more information.
The EVAL-LT7176P-1-AZ evaluation 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 EVAL-LT7176P-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. To fully explore the power system management features of the part, download the GUI software LTpowerPlay® onto the PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the fly, store the configuration in NVM, and view telemetry of voltage, current, temperature, and fault status. The NVM can be programmed up to three times.
