Product Overview
LTC®3789 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 input and output range and seamless, low noise transitions between operating regions, this is ideal for automotive, telecom and battery-powered systems. 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. Typical applications are automotive systems, distributed DC power systems, high power battery-operated devices, industrial control.
- Operating mode of the controller is determined through the MODE/PLLIN pin
- Single inductor architecture allows VIN above, below or equal to the regulated VOUT
- Programmable input or output current
- Synchronous rectification is up to 98% efficiency
- Current mode control
- Phase-lockable fixed frequency is 200kHz to 600kHz
- 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
- 28-lead (4mm × 5mm) plastic QFN package, –40°C to 125°C temperature rating
