Anyside™ Isolated Switch Controller with I²C Command and Telemetry

Hot swap integrated circuits are used to limit inrush current in either low-side or high-side DC applications. The application operating voltage is generally limited by the integrated circuits operating voltage, typically less than 100 volts. The LTM9100 allows the control of inrush current in both low-side and high-side applications operating up to 1000 VDC.

The LTM9100 provides a completely integrated isolated hot swap control and communication interface with isolated power. The isolation barrier allows the controller to float with the application, virtually eliminating operating voltage limitations, while providing flexible configuration. This video highlights the features and flexibility offered by the LTM9100.

Low EMI LED Driver with Synchronous Internal 2A Switches

The LT3922 40V, synchronous, Silent Switcher low EMI LED driver meets the demands of the next generation of LED systems.

These LED drivers require more features and higher performance than ever before. Higher efficiency prolongs battery life and reduces heat in space-constrained applications. Wide voltage ranges are needed to accommodate the many sources of energy and combinations of LEDs. Automotive converters must have low EMI. High PWM dimming ratios are needed for day and night display brightness control. Long off-times are needed between PWM pulses for machine vision and camera flashes. And all of these need the most advanced fault protection with the least number of components possible.

Wideband I/Q Demodulation for Zero-IF High Dynamic Range Receivers

5G LTE is on the way. These systems will require more bandwidth, and use more complex modulation formats. The LTC5586 High Linearity IQ Demodulator finds applications in 5G DPD PAs as an observation receiver, and in microwave/mm-wave gigabit backhaul receivers. Many features are digitally programmable, including RF input selection, baseband gain and DC offsets, quadrature gain/phase adjustments, and linearity adjustments.

Voltage Reference: Performance Plus Features

Demand for higher performance in mixed-signal circuits requires ever-better voltage references. But the highest-performance references of yesterday aren’t suitable, as they are generally simple products with few additional features.

With the development of high-performance bandgap references, plus improvements in process technology, we can design IC products that have unprecedented performance as well as a host of features, including low dropout, wide supply range, excellent line and load regulation, high output current capability, low noise and low drift. In addition, they may have self-protection features such as current and thermal limiting, as well as fault-protection like reverse-supply protection.

40A µModule Regulator with, 88% Efficiency, 0% Derating at 85°C, and 40°C Rise

The LTM4636 is a 40A step-down µModule switching regulator with 3D packaging construction for quicker heat dissipation and cooler operation in a small package. By stacking its inductor on top of a 16mm x 16mm BGA package, the LTM4636 benefits from the exposed inductor as a heat sink permitting direct contact with airflow from any direction to cool the device. The LTM4636 can deliver 40W (12VIN, 1VOUT, 40A, 200LFM) with only 40°C rise over the ambient temperature. Full-power 40W is delivered up to 83°C ambient and half-power 20W is supported at 110°C ambient.

The LTM4636 operates at 92%, 90% and 88% efficiency delivering 15A, 30A and 40A, respectively, to a 1V load (12VIN). The µModule regulator is scalable where four LTM4636s in current sharing mode deliver 160W with only 40°C rise and 88% efficiency (12VIN, 1VOUT, 400LFM).

Building a Wireless Sensor Network with Thousands of Nodes

A SmartMesh IP network consists of a highly scalable self-forming multi-hop mesh of nodes, known as motes, which collect and relay data, and a network manager that monitors and manages network performance and security, and exchanges data with a host application.
VManager software runs on an x86 virtual machine (VM), which can be installed on a variety of hardware platforms, from cloud servers down to low power embedded x86-based processors. The VManager software is delivered from Linear Technology as a pre-compiled and tested VM application that may run on VMWare, or Oracle VirtualBox VMs.

Precision Dual Output, High Current, Low Noise, Low Drift Reference

Precision and mixed signal applications usually require a voltage reference and at times several regulators or LDOs to support the analog circuitry. Separate regulators isolate the analog supply, digital supply and the voltage reference. The voltage reference supports the reference inputs of DACs and ADCs, and other devices that require a precise low noise voltage. The LT6658 satisfies the requirements of both, a voltage reference and regulator to provide an accurate voltage and enough current to supply power to sensitive precision analog blocks.
