Product Overview
LTC3780 is a high performance buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage. The constant frequency current mode architecture allows a phase lockable frequency of up to 400KHz. With a wide 4V to 30V (36V maximum) input and output range and seamless transfers between operating modes, it is ideal for automotive, telecom and battery-powered systems. The operating mode of the controller is determined through the FCB pin. For boost operation, the FCB mode pin can select among Burst Mode® operation, discontinuous mode and forced continuous mode. During buck operation, the FCB mode pin can select among skip-cycle mode, discontinuous mode and forced continuous mode. It is widely used in applications such as automotive systems, telecom systems, DC power distribution systems, high power battery-operated devices, industrial control.
- Synchronous rectification upto 98% efficiency
- Current mode control, phase-lockable fixed frequency from 200KHz to 400KHz
- Power good output voltage monitor, internal LDO for MOSFET supply
- Quad N-channel MOSFET synchronous drive, VOUT disconnected from VIN during shutdown
- Adjustable soft-start current ramping, foldback output current limiting
- Selectable low current modes, output overvoltage protection
- Shutdown supply current is 55µA typ at (VRUN = 0V, VSTBYMD = open)
- Operating temperature range from -40°C to 85°C
- Package style is 32-lead plastic QFN
