LTC3871ELXE in Linear Tech / ADI LT Series Family
The LTC3871ELXE family, manufactured by Analog Devices (formerly Linear Technology), is a high-performance, bidirectional, polyphase synchronous buck or boost switching regulator controller. Designed for 48V/12V dual-battery automotive and industrial power systems, it facilitates efficient energy transfer between two voltage domains. It operates as a buck converter from 48V to 12V or as a boost converter from 12V to 48V, controlled by an external signal, making it essential for mild-hybrid and energy recovery applications.
Variants in This Sub-Family
Variants within the LTC3871 sub-family, such as the LTC3871-1, typically differ in their control interface logic or specific fault management behaviors. For instance, the LTC3871-1 variant may offer refined polyphase synchronization features or adjustments to the spread spectrum modulation to improve electromagnetic interference (EMI) performance in sensitive automotive radio environments. Packaging options like the eLQFP ensure thermal reliability across different operating temperature grades.
