Isolated power converters support class B system EMI Levels

Analog Devices' latest generation of reinforced isolated power converters set a new benchmark for low component-level radiated emissions allowing systems to meet EN 55022/CISPR 22 Class B EMI standard requirements. The ADuM5020/6020 and ADuM5028/6028 series remove the need for expensive EMI mitigation techniques at the application level and simplify the EMI certification process reducing design cost and time. Emerging safety-critical applications, such as EV/HEV automotive battery monitoring and industrial PLC, need compact and dense isolated designs delivering size and weight savings, with strict emissions compliance, and reliable protection from high voltages for people and equipment. Use of these devices can obtain emissions targets on a two-layer PCB, which decreases the solution size by as much as 70% and lowers the material cost by 30% compared to a four-layer board. The new series of 500mW DC-DC power converters builds upon the company's iCoupler and isoPower chip-scale transformer technologies to support high-temperature operation up to 125C and the smallest eight-lead form factor.
