DC264A: Demo Board for the LTC1628 High Efficiency, 2-Phase Synchronous Step-Down Switching Regulator.

The LTC6363 family consists of four fully differential, low power, low noise amplifiers with rail-to-rail outputs optimized to drive SAR ADCs. The LTC6363 is a standalone differential amplifier, where the gain is typically set using four external resistors. The LTC6363-0.5, LTC6363-1, and LTC6363-2 each have internal matched resistors to create fixed gain blocks with gains of 0.5V/V, 1V/V, and 2V/V respectively. Each of the fixed-gain amplifiers features precision laser trimmed on-chip resistors for accurate, ultrastable gain and excellent CMRR.Applications 20-Bit, 18-Bit and 16-Bit SAR ADC Drivers Single-Ended-to-Differential Conversion Low Power ADC Drivers Level Shifter Differential Line Drivers Battery-Powered Instrumentation

The LTC7132 is a dual output PolyPhase DC/DC synchronous step-down monolithic regulator with an I2C-based PMBus compliant serial interface. The regulator employs a constant-frequency current mode architecture, together with a unique scheme to provide excellent performance in sub-milliohm DCR applications. The LTC7132 is supported by the LTpowerPlay? software development tool with graphical user interface (GUI).Programmable loop compensation allows the regulator to be compensated digitally. The switching frequency, channel phasing and device address can be programmed both by the digital interface as well as the external configuration resistors. Additionally, parameters can be set via the digital interface and stored in EEPROM. Both outputs have independent power good indicators and FAULT function.The LTC7132 can be configured to operate in discontinuous (pulse-skipping) mode or forced continuous conduction mode. Each channel can deliver up to 25A of loadcurrent; the total current capability will depend on the APPLICATIONS total power dissipations on both channels.POWER CONVERSION Wide VIN Range: 4.5V to 20V VOUT Range: 0.5V to 3.5V (with Ultralow DCR Setting); 0.5V to 5.5V (Typical DCR Setting) Accurate PolyPhase?

Demonstration circuit 2707B uses the LTC®4418 to arbitrate between two input supply rails, selecting the highest priority, valid supply to power the load. The V1 rail is defined to have higher priority and the V2 rail has lower priority. Both rails have individual overvoltage and undervoltage comparators for setting valid window thresholds with external resistive dividers. If the highest priority rail voltage V1 falls out of the defined window (overvoltage or undervoltage), the V2 rail, if it is valid, is enabled and powers the load. Two or more LTC4418s can be cascaded to provide switchover between more than two rails.
