LTC3871HLXE in Linear Tech / ADI LT Series Family
The LTC3871HLXE is a high-performance bidirectional buck/boost switching regulator controller from Analog Devices (Linear Technology). Engineered for 48V/12V automotive dual-battery systems, it operates in either buck or boost mode on command via a control signal. It features a polyphase architecture that allows for high current handling and efficiency across a wide input voltage range, making it a critical component for power distribution in mild-hybrid and autonomous vehicle platforms.
Variants in This Sub-Family
Variants within the LTC3871 series primarily differ in temperature grades and package options. The HLXE variant specifically denotes the high-temperature E-grade or H-grade specifications, ensuring reliable operation up to 150°C junction temperatures. Package variations include the 48-lead eLQFP, which features an exposed pad for enhanced thermal dissipation, essential for high-current applications where thermal headroom is limited.
