Pull Request Description

The LT7170/LT7170-1 are monolithic DC/DC synchronous step-down regulators that
deliver up to 20 A of continuous output current. The LT7170-1 option has two
switching phases that are connected to two inductors to drive a
single-regulated output supply.

Similarly, the LT7171/LT7171-1 are monolithic PolyPhase DC/DC synchronous
step-down regulators that also 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.

Both series offer quick, clean, low-overshoot switching edges deliver high
efficiency while minimizing electromagnetic interference (EMI) emissions.

An I2C-based PMBus 1.3-compliant serial interface allows control of device
functions while providing telemetry information for system monitoring. The
LT7170/LT7170-1 and LT7171/LT7171-1 are supported by the LTpowerPlay graphical
user interface (GUI) tool.
