The LTC3889 is a dual PolyPhase DC/DC synchronous step-down switching regulator controller with I2C-based PMBus compliant serial interface. This controller employs a constant-frequency, current-mode architecture, with high voltage input and output capability along with programmable loop compensation. The LTC3889 is supported by the LTpowerPlay™ software development tool with graphical user interface (GUI).
The EXTVCC pin supports voltages up to 14V allowing for optimized circuit efficiency and die temperature, and for the controller output to supply the chip power. Switching frequency, output voltage, and device address can be programmed both by digital interface as well as external configuration resistors. Parameters can be set via the digital interface or stored in EEPROM. Both outputs have an independent power good indicator and FAULT function.
The LTC3889 can be configured for discontinuous (pulseskipping) mode or continuous inductor current mode.
