Description
General part information
LT7171/LT7171-1 Series
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.APPLICATIONSCommunications, Storage, and Industrial SystemsData Center and Solid-State Drives
