The LT7171/LT7171-1 are monolithic PolyPhase DC/DC synchronous step-down regulators that deliver up to 20A of continuous output current. The LT7171-1 option has two switching phases that are connected to two inductors to drive a single-regulated output supply. The quick, clean, low-overshoot switching edges deliver high efficiency while minimizing electromagnetic interference (EMI) emissions. The I2C-based PMBus 1.3-compliant serial interface enables control of device functions while providing telemetry information for system monitoring. The LT7171/LT7171-1 are supported by the LTpowerPlay® graphical user interface (GUI) tool.
The controlled on-time valley current-mode control with 25ns typical minimum on-time enables a high switching frequency (fSW) at a low output voltage (VOUT) with excellent transient response in a small overall solution size.
VOUT, fSW, and phase are selectable using external configuration resistors. Settings can also be set via the PMBus interface or stored in the on-chip, three times programmable nonvolatile memory (NVM).
The LT7171/LT7171-1 use forced-continuous switching operation.

EVAL-LT7171-AZ
LT7171 16V PolyPhase Silent Switcher Step-Down Regulator with Digital Power System Management 2xLT7171, 40A
LT7171 16V PolyPhase Silent Switcher Step-Down Regulator with Digital Power System Management 2xLT7171, 40A
产品详情
Evaluation kit EVAL-LT7171-AZ has two single-phase monolithic DC/DC synchronous step-down regulators with a 2.9V to 16V input range featuring LT®7171. The output can supply up to 40A continuous load current. The Silent Switcher® structure is incorporated into the LT7171 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 LT7171 data sheet for more detailed information.
The EVAL-LT7171-AZ 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-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, and store the configuration in NVM, view telemetry of voltage, current, temperature, and fault status. The NVM can be programmed up to three times.
The EVAL-LT7171-AZ reserves two locations for evaluations, up to a total of four LT7171 IC parallel operations. For a detailed parallel configuration, refer to the LT7171 data sheet.
GUI Download
The software can be downloaded from LTpowerPlay.
The LT7171 data sheet gives a complete description of the part, operation, and application information. The data sheet must be read in conjunction with this demo manual for EVAL-LT7171-AZ.
For more details and instructions of the LTpowerPlay, refer to LTpowerPlay GUI for the LT7171 Quick Start Guide.
