Today, many electronic systems require power processing at higher voltages, while simultaneously demanding increased efficiency and low EMI/EMC emissions. The LTC7103 meets all of these challenges, with an unprecedented combination versatility and simplicity.
The LTC7103 is a 105V, 2.3A, synchronous step-down regulator that incorporates a proprietary architecture in a small 5mm x 6mm QFN package to achieve ultra-low EMI/EMC emissions without sacrificing efficiency. Operating from an input voltage between 4.4V and 105V, the LTC7103 has a no-load input current of only 2uA when regulating 48Vin to 3.3Vout.
Utilizing a unique average current mode architecture, the LTC7103 offers fast and accurate output current programming and monitoring without the need for an external sense resistor. Eight, pin-selectable fixed output voltages and optional internal loop compensation save board space and quiescent current while making the LTC7103 extremely easy to use.View the Video
The LTC2500-32 is a new and enabling approach to high-bandwidth, precision applications such as automated test equipment, control loops, seismology, and precision data acquisition. Analog performance of the SAR core is second to none - linearity is guaranteed 2 ppm maximum. Offset drift is 7 parts per billion per degree C, gain drift is 50 parts per billion, and the signal-to- noise ratio is 104dB at 1Msps. Such applications have traditionally used sigma delta ADCs, but the LTC2500 is much more versatile. Unlike a sigma delta ADC, the choice of digital filter is arbitrary, and the LTC2500-32 provides 78 filter options to suite a variety of applications. The filtered output achieves up to 148dB of dynamic range at 61sps. The LTC2500 also provides both no-latency data and filtered data simultaneously, matched perfectly in both time and analog accuracy.View the Video
The LTC3871 is a bidirectional synchronous buck or boost controller to step-down or step-up the voltage between the 12V and 48V batteries in dual battery automotive applications. The LTC3871 is a 100V/30V bidirectional two-phase synchronous buck or boost controller. It operates in buck mode or in boost mode. Either mode is configured on demand with an applied control signal. Up to 12 phases can be paralleled and clocked out-of-phase for high current applications up to 3kW. Four control loops, two for current and two for voltage, enable control of voltage and current on either the 48V or 12V outputs.View the Video

Selecting the appropriate input supply to power a system with multiple input power sources is not a trivial task. This video discusses challenges associated with the supply selection process, also known as prioritization. The LTC4419 and its features are introduced to show case how the product solves key prioritization challenges to provide a simple, low cost, power efficient solution. Special cases where input sources are rechargeable batteries require backup battery monitoring. The LTC4420, which is designed for these applications, and provides this function and more is introduced. The video concludes with a quick summary of a prioritization application using the LTC4419.View the Video
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.View the Video
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.View the Video

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.View the Video
