The LTC3880IUJ#PBF are dual, PolyPhase DC/DC synchronous step-down switching regulator controllers with an I2C-based PMBus compliant serial interface. The controllers use a constant frequency, current mode architecture that is supported by LTpowerPlay™ software development tool with graphical user interface (GUI).
Switching frequency, output voltage, and device address can be programmed using external configuration resistors. Parameters can be set via the digital interface or stored in EEPROM. Voltage, current, internal/external temperature and fault status can be read back through the bus interface. The LTC3880IUJ#PBF incorporates a 5V linear regulator.
