LTC7132IY#PBF

LTC7132 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. It is supported by the LTpowerPlay® software development tool with graphical user interface (GUI). Programmable loop compensation allows the regulator to be compensated digitally. The switching frequency, channel phasing and device address can be programmed both by the digital interface as well as the external configuration resistors. Additionally, parameters can be set via the digital interface and stored in EEPROM. Both outputs have independent power good indicators and FAULT function. It is used in application such as telecom, datacom and storage systems, industrial and point-of-load applications etc.
