    The LTC3886/LTC3886-1 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 LTC3886 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 LTC3886 can be configured for discontinuous (pulse-skipping) mode or continuous inductor current mode. The LTC3886-1 also includes a sequencing off feature to discharge very large output capacitors.

    Product Detail

    The DC2578A is a complete power chain, including a hot swap controller, an intermediate bus controller, and six point-of-load channels with power system management. The board demonstrates how to safely transfer power from a backplane, through an LTC4281 hot swap controller, through an LTC3886 step-down intermediate bus controller (IBC), and out through the point-of-load converters (POLs) that regulate load voltages. It shows the comprehensive set of power management, cooperation, and safety features of the Analog Devices solution, and showcases how easy it is to configure and manage the whole power hierarchy. Each regulated supply has the ability to sequence, trim, margin, supervise, measure, respond cooperatively to faults, and log fault information in nonvolatile memory. In addition, the onboard load pulser helps with optimizing the adjustable LTC3886 control loop response. The rich set of status and telemetry information provided by the entire system is consolidated and presented under one GUI interface — LTpowerPlay.
