LTC3884EUK#PBF

The LTC3884EUK#PBF is a dual output PolyPhase DC/DC synchronous step-down Switching Regulator Controller with an I?C-based PMBus compliant serial interface. The controller employs constant-frequency current-mode architecture, together with unique scheme to provide excellent performance for sub-milliohm DCR applications. It is supported by the LTpowerPlay® software development tool with graphical user interface (GUI). Programmable loop compensation allows the controller to be compensated digitally. Switching frequency, channel phasing output voltage and device address can be programmed both by the digital interface as well as external configuration resistors. Additionally, parameters can be set via the digital interface or stored in EEPROM. Both outputs have independent power good indicators and FAULT function. The LTC3884 can be configured for discontinuous (pulseskipping) mode or continuous inductor current-mode.
