Product Overview
The LTC3789IGN#PBF 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 600kHz, while an output current feedback loop provides support for battery charging. With a wide 4 to 38V (40V maximum) input and output range and seamless, low noise transitions between operating regions. The operating mode of the controller is determined through the MODE/PLLIN pin. The MODE/PLLIN pin can select between pulse-skipping mode and forced continuous mode operation and allows the IC to be synchronized to an external clock. Pulse-skipping mode offers high efficiency and low ripple at light loads, while forced continuous mode operates at a constant frequency for noise-sensitive applications. A PGOOD pin indicates when the output is within 10% of its designed set point.
- Single inductor architecture allows VIN above, below or equal to the regulated VOUT
- Programmable input or output current mode control
- No reverse current during start-up
- Power good output voltage monitor quad N-channel MOSFET synchronous drive
- VOUT Disconnected from VIN during shutdown
- True soft-start and VOUT short protection, even in boost mode
Applications
Automotive, Industrial, Automation & Process Control, Power Management
