The DC3097A-KIT is a demonstration system for the LTC2980-24 for the 24-channel I2C/SMBus/PMBus Power System Manager (PSM) with EEPROM. It consists of 4 circuit boards, namely one DC3094A board and three DC1361B boards. The LTC2980-24 monitors and controls 24 power supply rails which are provided by three DC1361B power supply boards that plug into the DC3094A. The system demonstrates the ability of the LTC2980-24 to sequence, trim, margin, supervise, monitor, and log faults for the twenty-four power supplies. Together these four boards form a sophisticated, 24-channel, digitally programmable and digitally managed power supply system. The board set contains twenty-four independent power supply rails, by having the three DC1361B boards. All 24 rails are based on LTM4603 DC/DC μModule® switching regulators. The DC1361B board is pre-configured with output voltages ranging from 0.8V to 3.3V. The power supply channels may be reconfigured to different output voltages by changing the feedback resistors. The LTC2980-24 can be configured to monitor current on odd numbered channels. The DC1361B board has been designed to allow the user to enable this feature on Channel 7. In this configuration, Channel 7 measures the current on Channel 6’s 1V output. The LTpowerPlay® graphical user interface (GUI) supports this demonstration system and enables complete control of all the features of the LTC2980-24. Together, the LTpowerPlay software and DC3094A hardware system create a powerful development environment for designing and testing configuration settings of the LTC2980-24. LTpowerPlay stores these settings in the LTC2980-24 internal EEPROM or in a project file. The software displays all the configuration settings and real time measurements from the Power System Management IC. Telemetry allows easy access and decoding of the fault log created by the LTC2980-24. The board comes pre-programmed with the EEPROM values appropriate for the twenty-four power supply rails. Just plug and play!

The LTC3246 is a switched capacitor buck-boost DC/DC converter with integrated watchdog timer. The device produces a regulated output (3.3V, 5V or adjustable) from a 2.7V to 38V input. Switched capacitor fractional conversion is used to maintain regulation over a wide range of input voltage. Internal circuitry automatically selects the conversion ratio to optimize efficiency as input voltage and load conditions vary. No inductors are required.The LTC3246?s reset time and watchdog timeout may be set without external components, or adjusted using external capacitors. A windowed watchdog function is used for high reliability applications. The reset input can be used for additional supply monitoring or be configured as a pushbutton reset.Low operating current (20?A without load, 1.5?A in shutdown) and low external parts count make the LTC3246 ideally suited for low power, space constrained automotive/ industrial applications. The device is short-circuit and overtemperature protected and is available in a thermally enhanced 16-pin MSOP package.Applications Automotive ECU/CAN Transceiver Supplies Industrial/Telecom Housekeeping Supplies Low Power 12V to 5V Conversion

Demonstration circuits 1053A-E through 1053A-H exercise the LTC3526L family of high efficiency synchronous boost converters, and are capable of operating with an input voltage range from 0.8V to 5.5V. The 2 × 2 mm DFN thermally enhanced package, high switching frequency (1MHz or 2MHz) and 550mA internal power switches provide a very tiny solution. The LTC3526L family also features output disconnect, and the input voltage can be greater or less than the output voltage. DC1053A-G features the LTC3526L-2 (Burst mode operation) and the DC1053A-H features the LTC3526LB-2 (Burst mode defeated). Both have a 2MHz switching frequency and use a 2.2µH inductor.
