Introduction

AI Translation

The LTC7871 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. An accurate current programming loop regulates the maximum current that can be delivered in either direction. The LTC7871 allows both batteries to supply energy to the load simultaneously by driving energy from either 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 an SPI-compliant serial interface, discontinuous or continuous mode of operation, OV/UV monitors, independent loop compensation for buck and boost operation, accurate inductor current monitoring and overcurrent protection.

The LTC7871 is available in a 64 pin 10mm×10mm LWE package.
