产品信息
产品概述
LTC3871 is a high performance bidirectional buck or boost switching regulator controller that operates in either buck or boost mode on demand. It regulates in buck mode from VHIGH-to-VLOW and boost mode from VLOW-to-VHIGH depending on a control signal, making it ideal for 48V/12V automotive dual battery systems. It allows both batteries to supply energy to the load simultaneously by converting energy from one battery to the other. Its proprietary constant-frequency current mode architecture enhances the signal-to-noise ratio enabling low-noise operation and provides excellent current matching between phases. Additional features include discontinuous or continuous mode of operation, OV/UV monitors, independent loop compensation for buck and boost operation, accurate output current monitoring and overcurrent protection. It is used in applications such as automotive 48V/12V dual battery systems, backup power systems etc.
