LT7171 PolyPhase DC/DC Step-Down Regulators

Analog Devices Inc. LT7171 PolyPhase DC/DC Step-Down Regulators can deliver up to 20A of continuous output current. The Analog Devices Inc. LT7171-1 variant utilizes two switching phases connected to two inductors to drive a single regulated output. The regulators' efficient operation minimizes electromagnetic interference (EMI) thanks to quick, clean, low-overshoot switching edges. Additionally, these regulators feature an I2C-based PMBus 1.3-compliant serial interface for device control and system monitoring telemetry. Management and configuration are facilitated through the LTpowerPlay® graphical user interface (GUI) tool.
