Demonstration circuit 2674A is a 140V high efficiency switching surge stopper featuring the LTC7862. The board operates from an input voltage range of 8V to 140V, and provides a 8V to 34V output from 0A to 10A. Its output voltage is programmed to be clamped at 34V (typical) with a minimum ride-through duration of 500ms to allow the load to operate through the input overvoltage events. Its output current is limited to protect against output short-circuit faults. A soft-start feature is utilized to control its output voltage slew rate at start-up and input voltage transients. This feature reduces current surge and output voltage overshoot. The demonstration board is able to achieve low insertion drop (210mV typical) by utilizing the low RDS(ON) N-channel MOSFETs and low DCR inductor. This board also includes optional reverse polarity protection circuit which protects the downstream loads up to −40V. The demonstration circuit is suitable for a wide range of automotive, industrial, and telecom applications. The LTC7862 high efficiency switching surge stopper protects loads from input high voltage transients. During an input overvoltage event, the LTC7862 controls the gate of two external N-channel MOSFETs and operate as a switching DC/DC step-down regulator. The output voltage is maintained at a safe level, allowing the loads to continue to operate through the input overvoltage events. During normal operation, the LTC7862 turns on the top external N-channel MOSFET continuously, passing the input voltage through to the output with minimal voltage drop. The LTC7862 also limits the maximum output current to protect against overcurrent and short-circuit faults. A programmable timer limits the time that the LTC7862 can spend switching during an overvoltage, overcurrent, or startup condition. When the timer expires, the external MOSFETs are turned off for a cooldown period and then the LTC7862 restarts. The timer limits how long the LTC7862 can switch when the power loss is relatively high, the components and thermal design can be optimized for normal pass-through operation. The LTC7862 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual for DC2674A. Proper board layout is essential for maximum thermal and electrical performance. See the data sheet sections for details. The LTC7862 is available in 20-lead TSSOP and QFN packages and two operating junction temperature grades: industrial (−40°C to 125°C) and high temperature automotive (−40°C to 150°C).

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 LT3967 and LT3960 data sheets give complete description of the parts, their operation and applications information.
