Space dictates a different design for DC-DC converters

Limited space requires DC-DC converters designed with thermal performance in mind, advises Timur Uludag of Würth Elektronik. An example of a typical industrial environment with multiple electronic applications and rail voltages is a warehouse. An industrial warehouse can hold complex conveyor systems with many sensors, actuators and control units. Each of these applications has its ...

Renesas fabs 22nm STT-MRAM

Renesas has developed a 22nm process for embedded spin-transfer torque magnetoresistive random-access memory (STT-MRAM). The test chip includes a 32Mbit embedded MRAM memory cell array and achieves 5.9-nanosecond (ns) random read access at a maximum junction temperature of 150°C, and a write throughput of 5.8-megabyte-per-second (MB/s). MRAM fabricated in BEOL is advantageous compared to flash ...
