Product Overview
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. This device 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. It is widely used in application such as automotive 48V/12V dual battery systems, backup power systems etc.
- Unique architecture allows dynamic regulation of input voltage, output voltage or current
- Operates with external gate drivers and MOSFETs, multiphase/multi-ICs operation upto 24 phases
- VHIGH supply voltage range is 6V to 100V, VLOW supply voltage range is 1.2V to 60V
- Synchronous rectification upto 98% efficiency
- ADI-proprietary advanced current mode control
- ±1% voltage regulation accuracy over temperature
- SPI compliant serial interface, operation status and fault report
- Phase-lockable frequency is 60KHz to 750KHz, optional spread spectrum modulation
- Operating temperature is -40°C to 150°C
- Package style is 64-lead plastic LQFP
