The LTC3882-1 is a dual, PolyPhase DC/DC synchronous step-down switching regulator controller with PMBus compliant serial interface. It uses a constant frequency, leading-edge modulation, voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.1V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. Up to four LTC3882-1 devices can operate in parallel for 2-, 3-, 4-, 6- or 8-phase operation.
System configuration and monitoring is supported by the LTpowerPlay™ software tool. The LTC3882-1 serial interface can read back input voltage, output voltage and current, temperature and fault status. Most operating parameters can be set via the digital interface or stored in internal EEPROM for use at power up. Switching frequency and phase, output voltage and device address can also be set using external configuration resistors.
