DC1786A: Demo Board for the LTC2871 RS232/RS485 Multiprotocol Transceivers with Integrated Termination.

The LTM2884 is a complete galvanically isolated USB 2.0 compatible ?Module? (micromodule) transceiver. An upstream supply powers both sides of the interface through an integrated, isolated DC/DC converter.The LTM2884 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device.The isolator ?Module technology uses coupled inductors and an isolated power transformer to provide isolation between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/?s.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the USB transceiver interface pins to local supplies and ?15kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition

Demonstration circuit 1801A is a dual output 1.5V/20A and 1.2V/20A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 14V. The demo board comes in two versions. The A version uses inductor DCR current sensing for high efficiency. The B version uses 2mΩ sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode topology of the LTC3838 allows for a fast load step response.

Demonstration circuit DC512B is a single battery switching step-down charge controller featuring the LTC4100. The recommended input power is 15 to 20V at 3.5A. A two-position jumper allows choice of protected output voltage range suitable for 3- and 4-Cell Li-ion batteries. Removal of the jumper allows full output voltage range. The maximum charge current is 4A. The demo board is initially configured for 12.6V at 3A for popular 3-cell Li-ion battery packs. LTC4100 will automatically charge a Smart Battery to termination as soon as input power is applied with a battery connected prior to power up. A VOUT pin automatically provides power to the system load from the wall adapter or battery. Status LEDs are provided for CHG, ACP, SMBALERT and SMBus activity.

Demonstration circuit 516A-A is a low output voltage, synchronous boost converter featuring the LTC3423. The LTC3423 is ideal for applications that require an output voltage between 1.5V to 2.6V from a single alkaline or NiCd/NiMH cell. A bias voltage (VDD) of 2.7V to 5.5V is required to power the internal circuitry. The input voltage (VIN) range is 1V to 1.6V, but once up and running, the device can operate with an input voltage as low as 0.5V. The output voltage is set at 1.8V. For a 1V minimum battery voltage, the LTC3423 can provide 350mA.

Demonstration circuit 534 is a fast transient response, very low dropout linear regulator featuring the 4A output current LT3150 linear regulator controller. The DC534 has an input voltage range of 1.1V to 10V and generates a jumper-selectable output voltage of 1.2V, 1.5V or 1.8V. With the LT3150 driving external N-channel MOSFETs as source followers, the DC534 can produce very fast transient response. The proper selection of the Rds(on) of the MOSFETs allows dropout voltages below 300 mV. These capabilities, plus its ability to maintain stable operation with ceramic output capacitors, make the DC534 voltage regulator ideally suited for low VIN-to-VOUT applications, such as microprocessor/microcontroller/FPGA power supplies.
