LT3999
Linear Technology Corporation announced the LT3999, a monolithic push-pull isolated DC/DC transformer driver with two 1A current limited power switches.

The LT3999 operates over an input voltage range of 2.7V to 36V, is targeted for power levels up to 15W and can produce a wide range of output voltages. This makes it well suited for automotive and other applications.

The programmable duty cycle and turns ratio of the transformer sets the output voltage. Several off-the-shelf transformers shown in the data sheet simplify the design.

76V, 1A Buck Converter with Adjustable Output Current Limit

Linear Technology announces the LTC3637, a 76V input-capable high efficiency buck converter that delivers up to 1A of continuous output current.

It operates from an input voltage range of 4V to 76V, making it suitable for automotive and other applications.

The LTC3637 utilizes a programmable peak current-mode design to optimize efficiency over a broad range of output currents. It delivers efficiencies as high as 90% and requires only 12µA of quiescent current, maximizing battery run time.

A user-programmable output current limit can set output current from 100mA to 1A as required by the application.

Texas Instruments (TI) unveiled the industry’s first inductance-to-digital converter (LDC), a new data converter category that uses coils and springs as inductive sensors to deliver higher resolution, increased reliability, and greater flexibility than existing sensing solutions at a lower system cost.

The industry’s first LDC device, LDC1000, is available to order today in a 16-pin, 4-mm by 5-mm SON package for US$2.95 in 1,000-unit quantities.

An automotive-qualified version will be available in the first half of 2014.

The LDC1000EVM, which includes an MSP430F5528 microcontroller (MCU), is available to evaluate the device and can be purchased today for US$29.00.

Comparing Ethernet and SerDes in ADAS applications

By Dave Lewis, Automotive Analog Marketing Manager, Texas Instruments

Abstract

Single-pair Ethernet is currently being deployed in automobiles over unshielded twisted pair (UTP) cable. Ethernet shows great promise as an in-vehicle networking technology for the connected car due to its ubiquity, tools, modularity, and IP support.

Although some infotainment display and camera-based advanced driver assistance system (ADAS) applications have introduced Ethernet to prove the technology, serializer/deserializer (SerDes) architectures (sometimes incorrectly called LVDS) typically are simpler, offer higher video quality, and are less expensive in these systems.

Let’s compare these two technologies in detail using a four-camera surround view application as an example.
