LT3970HMS in Linear Tech / ADI LT Series Family
The LT3970HMS sub-family, manufactured by Analog Devices Inc. (formerly Linear Technology), consists of compact micropower step-down switching regulators designed for high-efficiency power conversion. Operating over a wide input range of 4.2V to 40V, these buck converters utilize a Burst Mode architecture to maintain ultra-low quiescent current, making them ideal for systems that remain in standby for long periods. The LT3970HMS is specifically rated for high-temperature automotive and industrial environments.
Variants in This Sub-Family
The LT3970HMS variants primarily differ based on their thermal ratings and package options. The HMS suffix denotes an H-grade part, qualified for operation up to a junction temperature of 150°C, distinguishing it from standard E or I grades. While the core regulator remains consistent, specific part numbers may reflect lead-free finishes (PBF) or packaging formats like the 10-lead MSOP versus the DFN package, impacting thermal resistance and PCB footprint.
