The LTC7813 is a high performance synchronous Boost+Buck DC/DC switching regulator controller that drives all N-channel power MOSFET stages. It contains independent step-up (boost) and step-down (buck) controllers that can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that can be above, below, or equal to the output voltage. The LTC7813 operates from a wide 4.5V to 60V input supply range. When biased from the output of the boost regulator, the LTC7813 can operate from an input supply as low as 2.2V after start-up. The 34?A no-load quiescent current (both channels on) extends operating runtime in battery-powered systems.Unlike conventional buck-boost regulators, the LTC7813?s cascaded Boost+Buck solution has continuous, nonpulsating, input and output currents, substantially reducing voltage ripple and EMI. The LTC7813 has independent feedback and compensation points for the boost and buck regulation loops, enabling a fast output transient response that can be externally optimized.Applications Automotive and Industrial Power Systems High Power Battery Operated Systems

The LTC4282 hot swap controller allows a board to be safely inserted and removed from a live backplane. Using one or more external N-channel pass transistors, board supply voltage and inrush current are ramped up at an adjustable rate. An I2C interface and onboard ADC allows for monitoring of board current, voltage, power, energy and fault status.The device features analog foldback current limiting and supply monitoring for applications from 2.9V to 33V. Dual 12V gate drive allows high power applications to either share safe operating area across parallel MOSFETs or support a 2-stage start-up that first charges the load capacitance followed by enabling a low on-resistance path to the load.The LTC4282 is well suited to high power applications because the precise monitoring capability and accurate current limiting reduce the extremes in which both loads and power supplies must safely operate. Non-volatile configuration allows for flexibility in the autonomous generation of alerts and response to faults.APPLICATIONS Enterprise Servers and Data Storage Systems Network Routers and Switches Base Stations Platform Management

The LTC6419 is a dual very high speed, low distortion, differential amplifier. Its input common mode range includes ground, so that a ground-referenced single-ended or differential input signal can be DC-coupled, level-shifted, and converted to drive an ADC differentially.The gain and feedback resistors are external, so that the exact gain and frequency response can be tailored to each application. For example, the amplifier could be externally compensated in a no-overshoot configuration, which is desired in certain time-domain applications.The LTC6419 is stable in a differential gain of 1. This allows for low output noise in applications where gain is not desired. Each amplifier draws 52mA of supply current and has an independent shutdown pin which reduces current consumption to 100?A per amplifier.The LTC6419 is available in a compact 4mm ? 3mm?20?pin LQFN package and operates over a ?40?C to 125?C?temperature range.Applications Broadband I/Q Amplifiers Dual Differential ADC Driver High-Speed Data-Acquisition Cards Automated Test Equipment Time Domain Reflectometry Communications Receivers
