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 phaselockable frequency of up to 400KHz. With a wide 4V to 30V (36V maximum) input and output range and seamless transfers between operating modes, the LTC3780 is ideal for automotive, telecom and battery-powered systems. 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. Burst Mode operation and skip-cycle mode provide high efficiency operation at light loads while forced continuous mode and discontinuous mode operate at a constant frequency. Application includes automotive systems, telecom systems, DC power distribution systems, high power battery-operated devices and industrial control.
- A power good output pin indicates when the output is within 7.5% of its designed set point
- Fault protection is provided by output overvoltage comparator and internal foldback current limiting
- Operating mode of the controller is determined through the FCB pin
- Single inductor architecture allows VIN above, below or equal to VOUT
- Synchronous rectification: up to 98% efficiency, current mode control
- ±1% output voltage accuracy: 0.8V
VOUT 30V, phase-lockable fixed frequency: 200KHz to 400KHz - Internal LDO for MOSFET supply, quad N-channel MOSFET synchronous drive
- VOUT disconnected from VIN during shutdown, adjustable soft-start current ramping
- Selectable low current modes, output overvoltage protection
- 24-lead plastic SSOP package, -40°C to 125°C temperature range
