The LT8494 starts up from an input voltage range of 2.5V to 32V and once running it operates from inputs from 1 to 60V.

Linear Technology Corporation introduces the LTC4015, a highly integrated, high voltage multichemistry synchronous step-down battery charger controller with onboard telemetry functions. The device efficiently transfers power from a variety of input sources, such as wall adapters and solar panels, to a Li-Ion/Polymer, LiFePO4 or lead-acid battery stack and system load up to 35V.

Linear Technology has introduced the LT4276 LTPoE++, PoE+ and PoE-compliant Powered Device (PD) interface controllers for applications requiring 2 to 90W of delivered power. The LT4276 integrates a PD controller and an isolated switching regulator controller, capable of synchronous operation in both forward and flyback topologies with auxiliary power support.

Linear Technology Corporation announces the LTM4676A, a dual 13A or single 26A, current shareable up to 100A μModule step-down DC/DC regulator with PMBus serial digital interface. The digital interface enables system designers and remote operators to command and supervise a system’s power condition and consumption.

Linear introduces the LTC2984, a high performance digital temperature measurement IC that directly digitises RTDs, thermocouples, thermistors and external diodes with 0.1°C conformity and 0.001°C resolution.  The LTC2984 builds on Linear’s LTC2983 by adding Electrically Erasable Programmable Read-Only Memory (EEPROM) that stores user configuration data and custom sensor coefficients.

A bidirectional, programmable input current buck-boost supercapacitor charger with active charge balancing for 1- or 2-series supercapacitors has been introduced by Linear Technology. The proprietary low noise buck-boost topology does the work of two separate switching regulators, saving size, cost and complexity.

A dual 9A or single 18A µModule step-down DC/DC regulator with PMBus serial digital interface has been introduced by Linear Technology. The LTM4675 features an I²C-based interface, which enables system designers and remote operators to command and supervise a system’s power condition and consumption. 

Linear has introduced the LTC2348-18, an 18-bit, 8-channel simultaneous sampling SAR ADC with industry-leading performance and flexibility. While converting eight channels at 200ks/s per channel throughput, each SoftSpan input can be independently configured on a conversion-by-conversion basis to accept ±10.24, 0 to 10.24, ±5.12, or 0 to 5.12V signals.

Linear has announced the LT3088, a rugged 800mA wide VIN-range linear regulator. The device has an extended Safe Operating Area (SOA) compared to existing regulators, making it suitable for high input-to-output voltage and high output current applications where older regulators limit the output. The LT3088 uses a current source reference for single resistor output voltage settings and output adjustability down to 0.

A lithium battery backup power management system for 3.5-5V supply rails that must be kept active during a main power failure has been introduced by Linear Technology. Batteries provide considerably more energy than supercapacitors, making them superior for applications which require backup for extended periods of time.

  A family of I²C/SMBus address translators that enable multiple slaves with identical addresses to individually communicate with the master without conflicts has been introduced by Linear Technology. 

Linear has introduced an IO-Link (IEC 61131-9) reference design kit, which includes the DC2228A 8-port IO-Link master and DC2227A IO-Link device reference designs. With over 2.19m IO-Link nodes installed worldwide, the growing demand for larger networks is addressed by the reference design kit, which reduces IC count, development costs and time to market.

A dual 18A or single 36A µModule regulator with high precision output voltage regulation for 28nm and sub-28nm FPGAs, ASICs and MPUs has been released by Linear Technology. The core voltage of these advanced digital devices requires very accurate voltage regulation at steady state (DC) and at fast load current transients. 

Linear Technology has announced the LTC5576, an active double balanced upconversion mixer with very wide RF frequency range, extending from 3 to 8GHz. The LTC5576 enhances microwave transmitter and upconversion performance with linearity of 25dBm OIP3 and conversion loss of only 2dB at 8GHz, providing superior output signal quality compared to alternative passive mixers, which typically have 8dB of loss.

Linear has announced the LT8495, a current mode, fixed frequency SEPIC/boost DC/DC converter with an internal 2A, 70V switch. Quiescent current of only 9µA makes it suitable for always-on automotive systems, and its integrated Power-On Reset (POR) and watchdog timer offer enhanced system reliability required in automotive and industrial applications.

Designed for high dynamic range and high speed TransImpedance Amplifier (TIA) applications, the LTC6268-10 and LTC6269-10 single and dual 4GHz FET-input op amps have been released by Linear Technology.
