LTC388x Step-Down Controllers

Analog Devices Inc. LTC388x Step-Down Controllers are dual PolyPhase DC-DC synchronous step-down switching regulator controllers. Analog Devices LTC388x devices have an I2C-based PMBus-compliant serial interface. These controllers employ a constant-frequency, current-mode architecture with high-voltage input and output capability. The devices also have a programmable loop compensation and are supported by the LTpowerPlay™ software development tool with a graphical user interface (GUI).
