The LTC3887/LTC3887-1/LTC3887-2 are dual, PolyPhase DC/DC synchronous step-down switching regulator controllers with an I2C-based PMBus compliant serial interface. The controllers use a constant frequency, current mode architecture that is supported by LTpowerPlay® a software development tool with graphical user interface (GUI).
Switching frequency, channel phasing, output voltage, and device address can be programmed using external configuration resistors. Additionally, 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 LTC3887 has integrated gate drivers. The LTC3887-1 has three-state PWM pins to drive DrMOS power stages. The LTC3887-2 has gate drivers and no LDO and supports VIN up to 34V. The LTC3887 is an enhanced version of the LTC3880 with greater output voltage range and more digital features.
