Product Overview
The LTC3780EG#PBF is a high efficiency synchronous 4-switch Buck-boost Controller 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 4 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. The operating mode of the controller is determined through the FCB pin. For boost operation, the FCB mode pin can select among Burst ModeĀ® 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 ModeĀ® operation and Skip-Cycle mode provide high efficiency operation at light loads while forced continuous mode and discontinuous mode operate at a constant frequency.
- Single inductor architecture allows VIN above, below or equal to VOUT

- Ā±1% Output voltage accuracy (0.8V < VOUT < 30V)
- 200 to 400kHz Phase-lockable fixed frequency
- 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
- Fold back output current limiting
- Selectable low current modes
- Output overvoltage protection
Applications
Automotive, Communications & Networking, Power Management, Industrial
