The LTC3789 is a high-efficiency, synchronous, 4-switch buck-boost controller from Analog Devices. It is designed to operate from input voltages that are above, below, or equal to the output voltage, making it versatile for various power management applications.
Key features include a wide input voltage range of 4V to 38V and synchronous rectification for up to 98% efficiency. The controller utilizes a constant-frequency, current-mode architecture, allowing for a phase-lockable frequency from 200kHz to 600kHz. It also supports programmable input or output current and provides a Power Good output voltage monitor.
This controller is ideal for automotive systems, distributed DC power systems, high power battery-operated devices, and industrial control applications. It is available in a 28-lead SSOP package.
The LTC3789 offers true soft-start and output short protection, even in boost mode. Its seamless transitions between operating regions and low noise characteristics make it suitable for noise-sensitive applications when operated in forced continuous mode.
