Demonstration circuit 2686A is a 1.3A 8-switch matrix LED dimmer system with an I2C to CAN-physical transceiver featuring the LT3967 and LT3960. This demonstration circuit connects directly to a LED string and LED driver demonstration circuit to allow for independent dimming control of up to 8 channels of LEDs. A Linduino® One demonstration circuit is used to interface with the board and can connect in one of two different ways: Connect directly to a Linduino One demonstration circuit with a QuikEval™ ribbon cable. Connect using the LT3960 break-off board to connect to the I2C master device, but pass data over two twisted pair lines to the LT3960 on the main PCB. The LT3967 matrix dimmer features 8 individually con-trolled 1.3A rated floating NMOS switch channels and can support up to 56V of LEDs per device. The channels of the LT3967 can be configured for series connections, or non-series connections. Additional DC2686A demo circuits can be connected in series for higher number of LEDs, or in parallel to allow for higher current operation. Resistors are used to configure both the I2C slave address as well as the default start-up state. The default configuration for DC2686A sets the I2C address as 0000 with all LEDs off. See the LT3967 data sheet for details. The LT3960 I2C to CAN-Physical transceiver is used to send and receive I2C data through harsh or noisy environments at up to 400kb/s using the CAN-Physical layer for differential signaling over twisted pair connections. Both SDA and SCL data lines are converted to differential signals and are shared between devices connected to the bus. This allows for physical separation of the I2C source with the LT3960 transceiver board and the LT3967 main PCB along with the LED driver. This demo circuit is designed to be easily configured and interfaced with a compatible low output capacitance LED driver and LED string. It can easily be directly attached to a buck LED driver or a floating buck-mode LED driver. More sophisticated setups with series matrix dimmers for higher number of LEDs such as 12 or 16 is possible. Please consult factory applications for details or look for more details on analog.com.

The data sheets must be read in conjunction with the demo manual for demonstration circuit DC2686A. The LT3967EFE is assembled in a thermally enhanced 28-lead TSSOP package. The LT3960EMSE is assembled in a 10-lead MSOP package.

The LTC4376 is a 7A ideal diode that uses an internal 15m? N-channel MOSFET to replace a Schottky diode when used in diode-OR and high current diode applications. The LTC4376 reduces power consumption, heat dissipation and PC board area.The LTC4376 controls the forward voltage drop across the internal MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. The LTC4376 also easily ORs power sources to increase total system reliability.With its low operating voltage, small solution size and the ability to withstand reverse input voltage, the LTC4376 excels in portable battery applications. A shutdown mode is available to reduce the quiescent current to 9?A. The SHDN pin can also control the forward current path when an external MOSFET is used in series with the internal MOSFET in a back-to-back configuration.Applications Automotive Battery Protection Redundant Power Supplies Portable Battery Devices Computer Systems/Servers

The LTC2972 is a 2-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. PMBus commands support power supply sequencing, precision point-of-load voltage adjustment and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include over and under voltage and temperature threshold limits for two power supply output channels as well as over and under voltage threshold limits for a single power supply input channel. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors two output voltages, two output currents, two external temperatures, input voltage and current, and die temperature. Input power, energy, and output power are also calculated. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple ADI Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.APPLICATIONS Computers and Network Servers Industrial Test and Measurement High Reliability Systems Video and Medical Imaging

Demonstration circuit 2754A extends an I2C based QuikEval™ interface to up to 450 feet and features the LTC4331. In order to realize the QuikEval interface, this demo circuit includes two complete I2C extenders and a remote side power supply formed from an LT3461 boost converter and two LT1761 LDOs. The LTC4331 is a SMBus compatible I2C slave device extender designed for operation in high noise industrial environments. The I2C/SMBus is extended over a single twisted pair by a ±60V fault protected differential transceiver. The LTC4331’s extended 15V common mode voltage range allows it to bridge across different ground potentials. When used as a QuikEval extender, the DC2754A requires the use of the DC2026 USB serial adapter. The DC2754A is NOT compatible with the DC590 USB serial adapter because the DC590 does not support clock stretching. The DC2754A’s jumpers and turrets allow easy re-configuration for use in other applications and/or demonstrating other application circuits. The circuit board is fabricated with a score between the local and remote sides to allow physical separation. The link cable connections are made using either pluggable terminal blocks or an Ethernet cable. Two complete I2C extenders are present. The first extender has a full set of diagnostic LEDs, jumpers, turrets and large (0805) resistors for simple user reconfiguration and connection for customer specific application(s). The second extender is configured specifically for the QuikEval EEPROM with no LEDs; however, it may be reconfigured and used for customer specific application(s) via 0603 jumpers and resistors and unpopulated test points on 0.1" centers. The LTC4331 data sheet gives a complete description of the part, its operation and application information. The data sheet should be referred to when reading this demo manual. The LTC4331 is available in a 20-lead QFN package and three temperature grades (commercial 0°C to 70°C, industrial –40°C to 85°C, and high temperature –40°C to 125°C).

The LTC6754 includes 4.5mV of hysteresis to minimize instability. For the QFN package, a separate pin is available to set the hysteresis from 0mV (off) up to 40mV. The QFN version also features output latching to provide the ability to capture the state of the comparator. The DC2767 provides a connection to set the hysteresis or for output latching. LTC6754 is ideally suited for high frequency line driver and clock recovery circuits.
