LTC3780IG Description

Short technical summary and product information.

The LTC3780IG from Analog Devices is a high-performance buck-boost switching regulator controller designed for applications requiring efficient voltage conversion. It features a single inductor architecture, allowing the input voltage (VIN) to be above, below, or equal to the output voltage (VOUT).

Key electrical specifications include a wide VIN range of 4V to 36V, synchronous rectification for up to 98% efficiency, and current mode control. The output voltage accuracy is ±1%, with a minimum typical output voltage of 0.8V and a maximum typical output voltage of 30V. The device supports a phase-lockable fixed frequency operation between 200kHz and 400kHz. It also includes features like a power good output voltage monitor, internal LDO for MOSFET supply, and quad N-channel MOSFET synchronous drive.

This controller is available in a 24-lead SSOP package. The operating temperature range is -40°C to 125°C. Additional features include adjustable soft-start current ramping, foldback output current limiting, selectable low current modes, and output overvoltage protection.
