The Analog Devices Inc. LTC3119IUFD is a highly efficient, synchronous buck-boost DC/DC converter. This device is designed to deliver a stable output voltage from input voltages that are above, below, or equal to the output voltage. It features an adjustable output voltage ranging from 0.8V to 18V, with a maximum output current capability of 5A. The LTC3119IUFD operates with a wide input voltage range of 2.5V to 18V and offers a configurable switching frequency from 400kHz to 2MHz, allowing for optimization between efficiency and component size. Its topology incorporates a synchronous rectifier for enhanced efficiency. The 28-WFQFN exposed pad package (28-QFN (4x5)) facilitates effective thermal management. This component is suitable for applications in battery-powered systems, portable electronics, and general power conversion where flexible voltage regulation is required. The operating temperature range is specified as -40°C to 125°C (TA).
