LTC7871JLWE Integrated Circuit Chip Synchronous Bidirectional Buck-Boost PolyPhase Controller with 60kHz ~ 750kHz Switching Frequency for Humanoid Robots

Description
Part Number: LTC7871JLWE Series: PolyPhase
Number Of Outputs: 6 Topology: Buck-Boost
Frequency - Switching: 60kHz ~ 750kHz Operating Temperature: -40°C ~ 150°C (TJ)

LTC7871JLWE Integrated Circuit Chip Synchronous Bidirectional Buck-Boost PolyPhase Controller LQFP-64
Product Overview

LTC7871JLWE is a high-performance six-phase synchronous bidirectional buck-boost PolyPhase controller, specially optimized for high-power 48V lithium battery powered humanoid robots with dual 48V main bus and 12V servo auxiliary rail architecture.

LTC7871JLWE supports bidirectional energy flow: buck mode converts 48V high voltage to 12V for joint servo drivers, while boost mode recovers regenerative braking energy from motors back to the main 48V battery, greatly improving robot battery endurance.
