deion

　　the ltc®3880/ltc3880-1 are dual, polyphase dc/dc synchronous step-down switching regulator controllers with an i2c-based pmbus pliant 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 canbeprogrammedusingexternal configurationresistors. 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 ltc3880 incorporates a 5v linear regulator while the ltc3880-1 uses anexternal 5v supply forminimumpower loss.
