Product Overview

The LTC3880EUJ#PBF is a dual PolyPhase DC/DC synchronous step-down Switching Regulator Controller with an I²C-based PMBus compliant serial interface. The controller uses a constant frequency, current-mode architecture that is supported by LTpowerPlay™ software development tool with graphical user interface (GUI). Switching frequency, output voltage and device address can be programmed using external configuration resistors. Parameters can be set via the digital interface or stored in EEPROM. Voltage, current, internal/external temperature and fault status can be read back through the bus interface. The controller incorporates a 5V linear regulator.
  • ±0.5% Output voltage accuracy over temperature
  • Integrated 16-bit ADC
  • Internal EEPROM and fault logging
  • Integrated powerful N-channel MOSFET gate drivers power conversion
  • Analog current mode control loop
  • Supports power-up into pre-biased load
  • Accurate PolyPhase® current sharing for up to 6 phases
