The LTC3884/LTC3884-1 are dual output PolyPhase DC/DC synchronous step-down switching regulator controllers with an I2C-based PMBus compliant serial interface. The controllers employ a constant-frequency current mode architecture, together with a unique scheme to provide excellent performance for sub-milliohm DCR applications. The LTC3884/LTC3884-1 are 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 LTC3884-1 has all the features that the LTC3884 has except the LTC3884 includes MOSFET gate drivers while the LTC3884-1 does not.
Applications
