The LT1374CR-SYNC#TR is a monolithic switching regulator integrated circuit designed for efficient step-down and SEPIC conversion applications. Manufactured by LT, this device provides an adjustable positive output voltage ranging from 2.42V to 21.5V, driven by an input supply between 5V and 25V. It supports continuous switch currents up to 4.5A and operates at a fixed 500kHz switching frequency, allowing for compact external passive components.
The regulator does not include synchronous rectification, making it suitable for cost-sensitive designs requiring reliable power management. Packaged in a surface-mount TO-263-8 D²Pak (7 leads plus tab) case, it ensures efficient thermal dissipation for junction temperatures up to 125°C. This component is well-suited for point-of-load regulation in servers, routers, telecom equipment, industrial controls, and automotive electronics where medium-to-high current delivery and wide input voltage tolerance are required.
The input voltage range is 5V to 25V, and the output voltage can be adjusted from 2.42V to 21.5V.
It is available in a surface mount TO-263-8 (D2PAK) package with 7 leads plus tab.
The operating junction temperature range is 0°C to 125°C.
The switching frequency is fixed at 500kHz.
It supports both buck and SEPIC topologies.
The maximum switch current is 4.5A.
