Linear Technology Corp. introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold crank.
Linear Technology introduces over 53 µModule® (micromodule) power products with SnPb BGA packages, targeting applications where the use of tin-lead soldering is preferred. µModule power products with SnPb BGA packages are offered in four DC/DC converter categories: (1) step-down or buck converters with single and multiple outputs, (2) buck-boost converters, (3) isolated converters, and (4) converters with PMBus digital telemetry with READ and WRITE data capability.
Linear Technology Corp. introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. The LTC7813 operates from an input voltage of 4.5 to 60 V during start-up and maintains operation down to a 2.2 V input after start-up. The boost converter can produce an output voltage up to 60 V and the buck converter produces an output voltage ranging from 0.8 to 60V with the entire system achieving an efficiency as high as 98%.
Linear Technology Corp. introduces the LTC2873, an RS485/RS232 multiprotocol transceiver in a small 20 mm² package. The LTC2873 integrates all the functions necessary to provide the most compact multiprotocol IC available today. Supporting ±26 kV HBM ESD bus protection, the LTC2873 provides a robust software-selectable interface for 3 to 5.5 V systems.
Linear Technology Corp. introduces the LTC4125, a wireless power transmitter, complementing our wireless receiver ICs for the wireless charging market. The LTC4125 is a simple, high performance monolithic full bridge resonant driver, capable of delivering up to 5W of power wirelessly to a companion receiver. It functions as the transmit circuit component in a complete wireless power transfer system comprised of transmit circuitry, transmit coil, receive coil and receive circuitry.
Linear Technology Corp. introduces the LTC2380-24, a breakthrough no latency 24-bit 2 Msps successive approximation register (SAR) analog-to-digital converter (ADC). The LTC2380-24 features an integrated digital filter that averages 1 to 65,536 conversion results real time, dramatically improving the dynamic range from 101 dB at 1.5 Msps to 145 dB at an output data rate of 30.5 sps.
Linear Technology Corp. announces the LT8331, a current mode step-up DC/DC converter with an internal 500 mA, 140 V switch. It operates from an input voltage range of 4.5 to 100 V, making it suitable for use with a wide range of input sources found in industrial, transportation and avionic applications. The LT8331 can be configured as either a boost, SEPIC, flyback or inverting converter. Its switching frequency is programmable from 100 to 500.
Linear Technology Corp. introduces the LTC4282, an energy monitoring hot swap controller with dual MOSFET drive to enable 100 A and higher current board designs. The LTC4282 ensures safe board insertion and removal from live 2.9 to 33 V backplanes by controlling external N-channel MOSFETs to gently power up capacitors, avoiding sparks, connector damage and system glitches. High current hot-pluggable boards utilize parallel MOSFETs to reduce voltage drop.
