PRODUCT SHOWCASE KCS sells 500,000 TraceME LoRa units KCS BV is proud to announce that a new milestone was reached in Q3 2021 – over 500,000 ‘TraceME’ LoRa and other tracking units have been sold. Since KCS have integrated new LPWAN (Low-Power Wide Area Network) technologies, new use cases and massive IoT deployments became possible. Switching from traditional GPS/ GPRS systems to LPWAN based systems resulted in reduced costs and increased battery lifespans to more than 10 years in some cases. It has now become feasible for countless industries and businesses to implement IoT. Some examples of how to use it include smart waste management, temperature-controlled transport, smart road signs and large-scale asset tracking such as E-bikes. In 2022 and beyond, KCS will continue to build on its existing TraceME products to enable new use cases and provide further enhancements. KCS remains dedicated to showing why it is a safe choice for any large-scale IoT deployment. Please visit www.trace.me for more information. KCS TraceME Kuipershaven 22, 3311AL Dordrecht Netherlands www.trace.me New automotive boost controller from Analog Devices Analog Devices (Maxim) have introduced a highly efficient multi-phase synchronous boost controller that regulates high-power Class-D amplifiers in automotive infotainment systems. The MAX25203 features both programmable gate drive voltage and current limit blanking time, as well as accurate current balancing, and operates at a high switching frequency, all while shrinking PCB space by 36%. The MAX25203 joins ADI’s family of automotive boost controllers that include the MAX25201 and MAX25202 single/dual boost controllers, both designed for lower power applications. You can buy evaluation boards, view the data sheet and order samples from Maxim’s website at: https://bit.ly/ MAX25203Product The MAX25203 controller starts with a battery input voltage from 4.542V, and operates down to 1.8V after start-up. It sustains an absolute maximum output voltage of up to 70V and features a low shutdown supply current of 5µA. The Max25203 is useful to generate backlight and Class-D audio amplifier voltages and also offers I2C bus diagnostics including die temperature, phase current monitoring and optional true shutdown to improve system reliability. Output voltage is scalable via the PWM input or I2C interface and a syncout feature supports additional phases for higher power systems. The MAX25203 synchronous boost controller features: • Factory programmable gate drive voltage from 5.5-10V increases power density by reducing MOSFET Rds(on) loss for higher efficiency and lower cost. • Programmable current limit blanking time supports short peak current events without power supply overdesign for lower solution cost. • ±5% current share accuracy from phase-to-phase reduces inductor size. • Resistor programmable switching frequency up to 2.1MHz improves EMI and reduces external components’ size and number.
