LTC3882IUJ#PBF

LTC3882 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 0.5V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. This device system configuration and monitoring is supported by the LTpowerPlay® software tool. The device’s serial interface can be used to read back input voltage, output voltage and current, temperature and fault status. A wide range of operating parameters can be set via the digital interface or stored in internal EEPROM for use at power up. It is used in application such as high current distributed power systems, servers, network and storage equipment, intelligent energy efficient power regulation, industrial/telecom/ATE systems etc.
