ADI Launches SEPIC Controller Supporting Wide Input Range
Published2017.04.21 10:46Maximizing Efficiency Through On-Resistance Utilization
Analog Devices announced the launch of LTC1871X, a new current mode, boost, flyback, or SEPIC controller that supports a wide input range.
This product is characterized by its ability to drive N-channel power MOSFETs and requires minimal external components. Designed with emphasis on low to medium power applications, this product utilizes the on-resistance of power MOSFETs, eliminating the need for a separate current sense resistor and maximizing efficiency. The LTC1871X is optimized for high-temperature environments up to 175°C.
The LTC1871X has an extremely wide input voltage range of 2.5V to 36V, making it ideal for high-temperature applications such as oil drilling equipment with supply voltage ranges of 3V to 36V. Since the electrical parameters are 100% tested at 175°C, it provides ±2% VREF accuracy across the entire temperature range of –40°C to 175°C.
The LTC1871X can flexibly be used in boost, SEPIC, or flyback topologies, making it ideal for various battery-powered applications commonly found in downhole drilling applications. The LTC1871X's Burst Mode® operation features low quiescent current consumption, making it well-suited for applications requiring extended battery runtime. Specialized copper (Cu)/nickel (Ni)/gold (Au) pad plating ensures longer lifespan in high-temperature environments, and the compact MSOP-10 package provides a very compact solution footprint.

ADI Launches SAR ADC with Built-in Picoampere Input Buffer
Analog Devices announced the launch of LTC2358-18, a new 18-bit 8-channel simultaneous sampling SAR (successive approximation register) ADC with an integrated picoampere (pA) input buffer. In particular, when board space is limited, the LTC2358-18 reduces space and cost by eliminating the front-end signal conditioning circuits commonly required to drive switched capacitor ADC inputs that require buffering. It can reduce 3 amplifiers, 6 resistors, and 2 capacitors per channel, thereby reducing a total of 88 components across 8 channels. This delivers significant reductions in BOM (bill of materials) cost as well as board area, while also providing more than 40% reduction in power consumption.

ADI Launches Accelerometer for Long-term Monitoring of High-Value Assets
Analog Devices has launched a next-generation accelerometer designed to enable long-term monitoring of the physical condition of high-value assets. The ADXL372 micropower high-g MEMS accelerometer, which achieves ultra-low power consumption, is a product focused on Internet of Things solutions where devices may experience shock or collision during storage, transport, or use, potentially adversely affecting functionality, safety, and reliability. The ADXL372 accelerometer, an ultra-low power MEMS sensor, can start operation immediately through its "instant on" feature and capture the complete waveform, thereby significantly reducing standby power consumption. While waiting to detect impact, only a current below 2 microamperes is required, so when the sensor is used in a motion detection activation system, it can operate for several years on a single small battery.
