LTC7132
25A, Dual PolyPhase Regulator with
Digital Power System Management
FEATURES n DESCRIPTION PMBus/I2C Compliant Serial Interface The LTC®7132 is a dual output PolyPhase DC/DC synchronous step-down monolithic regulator with an I2C-based
PMBus compliant serial interface. The regulator employs
a constant-frequency current mode architecture, together
with a unique scheme to provide excellent performance
in sub-milliohm DCR applications. The LTC7132 is supported by the LTpowerPlay® software development tool
with graphical user interface (GUI). – Telemetry Read-Back Includes VIN, IIN, VOUT, IOUT, Temperature and Faults
– Programmable Voltage, Current Limit, Digital SoftStart/Stop, Sequencing, Margining, OV/UV/OC
