The LTC4230 is a 3-channel Hot Swap? controller that allows a board to be safely inserted and removed from a live backplane. Internal high side switch drivers control the gates of external N-channel MOSFETs for supply voltages ranging from 1.7V to 16.5V. The LTC4230 provides soft-start and inrush current limiting during the programmable start-up period.On-chip current limit comparators provide dual level circuit breaker protection. The slow comparators trip at VCCn?? 50mV and activate in 10?s or are programmed by an external filter capacitor. The fast comparators trip at VCCn?? 150mV and typically respond in 500ns.Each FBn?pin monitors its own output supply voltage and signals its RESET pin. The ON pin turns the chip on and off and can be used for a reset function. The LTC4230 also provides additional functions including fault indication, autoretry or latchoff modes, programmable current limit response time based on the FAULT and FILTER pins? functionality.Applications Electronic Circuit Breaker Hot Board Insertion and Removal (Either On Backplane or On Removable Card) Industrial High Side Switch/Circuit Breaker

The LTC1604 is a 333ksps, 16-bit sampling A/D converter that draws only 220mW from ?5V supplies. This high performance device includes a high dynamic range sample-and-hold, a precision reference and a high speed parallel output. Two digitally selectable power shutdown modes provide power savings for low power systems.The LTC1604's full-scale input range is ?2.5V. Outstanding AC performance includes 90dB S/(N+D) and ?100dB THD at a sample rate of 333ksps.The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 15MHz bandwidth. The 68dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.The ADC has ?P compatible,16-bit parallel output port. There is no pipeline delay in conversion results. A separate convert start input and a data ready signal (BUSY) ease connections to FlFOs, DSPs and microprocessors.Applications Telecommunications Digital Signal Processing Multiplexed Data Acquisition Systems High Speed Data Acquisition Spectrum Analysis Imaging Systems

The LTC1628/LTC1628-PG are high performance dual step-down switching regulator controllers that drive all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows adjustment of the frequency up to 300kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase.OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The precision 0.8V reference and power good output indicator are compatible with future microprocessor generations, and a wide 3.5V to 30V (36V maximum) input supply range encompasses all battery chemistries.A RUN/SS pin for each controller provides both soft-start and optional timed, short-circuit shutdown. Current foldback limits MOSFET dissipation during short-circuit conditions when overcurrent latchoff is disabled. Output overvoltage protection circuitry latches on the bottom MOSFET until VOUT returns to normal. The FCB mode pin can select among Burst Mode, constant frequency mode and continuous inductor current mode or regulate a secondary winding. The LTC1628-PG includes a power good output pin that replaces the FLTCPL, fault coupling control pin of the LTC1628.Applications Notebook and Palmtop Computers, PDAs Battery Chargers Portable Instruments Battery-Operated Digital Devices DC Power Distribution Systems
