July 01, 2011 // By Electronics EETimes

Modern electronics systems require high performance point of load power supplies with advanced and intelligent power management. Linear Technology's LTC®3880 combines a best in class analog switching regulator controller with precise mixed signal data conversion for unsurpassed ease of power system design and management.

The analog current mode control architecture of LTC3880 ensures best loop stability, transient responses, accurate DC and dynamic current sharing. In addition to that, the LTC3880 is a comprehensive digital power manager with over 100 PMBus compliant commands and on-chip EEPROM. On-chip precision data converters and EEPROM allow for the capture and nonvolatile storage of regulator configuration settings and telemetry variables. LTC3880 is supported by LTpowerPlayTM Design Tool, an easy-to-use and powerful graphical user interface program. The LTC3880 can be used for computer, datacom, telecom equipment and storage systems.
