The LTC3789EGN#TRPBF is a high-performance buck-boost switching regulator controller from Linear Technology. It is designed for applications requiring input voltages that can be above, below, or equal to the output voltage. The controller features a constant-frequency, current-mode architecture, allowing for a phase-lockable frequency up to 600kHz.
Key electrical specifications include a wide input voltage range of 4V to 38V and an output voltage accuracy of 1%. It supports synchronous rectification for efficiencies up to 98%. The device also includes an internal 5.5V LDO and a power good output monitor.
This controller is suitable for automotive systems, distributed DC power systems, high-power battery-operated devices, and industrial control applications. It is available in 28-lead QFN (4mm x 5mm) and 28-lead SSOP packages, both suitable for surface mounting.
The LTC3789 offers features such as true soft-start, output voltage short protection, and seamless transitions between operating regions, making it ideal for demanding power management solutions.
The input voltage range is 4V to 38V.
The output voltage can be adjusted from 0.8V to 38V.
The switching frequency is phase-lockable from 200kHz to 600kHz.
The efficiency is up to 98% with synchronous rectification.
The output voltage accuracy is 1%.
The internal LDO provides a 5.5V output.
The device is available in a 4x5 QFN-28 package and an SSOP-28 package, both surface mount.
