The LTC3789EGN#TRPBF by ADI Electronics is a high-performance buck-boost switching regulator controller. It is designed to operate from input voltages that are above, below, or equal to the output voltage, offering flexibility in power system design.
Key features include a wide input voltage range of 4V to 38V, with a maximum rating of 40V. The controller boasts synchronous rectification for up to 98% efficiency and a constant-frequency, current-mode architecture. It supports a phase-lockable frequency range from 200kHz to 600kHz. The output voltage accuracy is 1%, with a configurable output voltage range from 0.8V to 38V.
This controller is ideal for applications requiring seamless transitions between operating regions and low noise. It supports programmable input or output current and includes a Power Good output voltage monitor. The LTC3789 is available in compact 28-lead QFN (4mm x 5mm) and SSOP packages, making it suitable for space-constrained designs.
Applications include automotive systems, distributed DC power systems, high-power battery-operated devices, and industrial control. The device features true soft-start and output short protection, even in boost mode, enhancing system reliability.
