Demonstration circuit 1567B features the LTC4274, a single power sourcing equipment (PSE) controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet (PoE) systems. The LTC4274 is configured in the DC1567B as a midspan power injector where data comes in from an existing network system and out, along with power, to a powered device (PD). The LTC4274 autonomously detects and classifies a PD, turns power on to the port, and disconnects port power without the need for a microcontroller. A two second backoff timer supports the midspan configuration. A 55V nomical supply is recommended to power the demo board.

Demonstration circuit 1568A is a 2A monolithic multichemistry battery charger for solar power applications featuring the LT3652EDD. The LT3652 is a complete mid-power Li-Ion battery charger that can operate over a wide input voltage range. The charger employs a 3.3V float voltage feedback reference that allows the battery float voltage to be adjusted up to 14.4V. The LT3652 has an input voltage regulation loop which reduces charge current if the input falls below a programmed level, set with a resistor divider. The circuit provides CC/CV charging with a 2A maximum charge current that is programmed by a sense resistor.

The LTC2382-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2382-16 has a ?2.5V fully differential input range. The LTC2382-16 consumes only 6.5mW and achieves ?2LSB INL max, no missing codes at 16-bits and 92dB SNR. The LTC2382-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The fast 500ksps throughput with no cycle latency makes the LTC2382-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2382-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate. The LTC2382-16 features a proprietary sampling architecture that enables the ADC to begin acquiring the next sample during the current conversion. The resulting extended acquisition time of 1.25?s allows the use of extremely low power ADC drivers.Applications Medical Imaging High Speed Data Acquisition Portable or Compact Instrumentation Industrial Process Control Low Power Battery-Operated Instrumentation ATE?

DC1582B-B: Demo Board for the LTC3108-1 Ultralow Voltage Step-Up Converter and Power Manager.

Demonstration circuit 1587A is a boost converter optimized for relatively high impedance, very low voltage input power sources. It allows a user to quickly evaluate the LTC3105 boost converter and LDO regulator. Capable of operating with an input voltage as low as 250mV and as high as 5V, the circuit features maximum power point control (MPPC). Jumpers on the circuit board allow the user to select several MPPC voltages, three boost output voltages and three LDO regulator output voltages. Also included are jumpers for shutdown and for selecting an external pull-up voltage for the power good status output. Terminals are provided for input and output connections, power good output and external power good supply input, shutdown input, and provisions for external MPPC resistor and MPPC diode input. This demonstration board is especially designed for low power solar cell applications.

DC1593A-A: Demo Board for the LTC2635-12 Quad 12-Bit I2C VOUT DACs with 10ppm/°C Reference.

The LTC4219 is an integrated solution for Hot Swap applications that allows a board to be safely inserted and removed from a live backplane. The part integrates a Hot Swap controller, power MOSFET and current sense resistor in a single package for small form factor applications. The LTC4219 provides separate inrush current control and a 10% accurate 5.6A current limit with foldback current limiting. The current limit threshold can be adjusted dynamically using an external pin. Additional features include a current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and a MOSFET temperature monitor output. Thermal limit and power good monitoring are also provided. The power good detection level and foldback current limit profile are internally preset for 5V (LTC4219-5) and 12V (LTC4219-12) applications.Applications RAID Systems Server I/O Cards Industrial
