48V Buck Converter Helps MHEVs Meet Fuel Emission Standards

 

48V Buck Converter Helps MHEVs Meet Fuel Emission Standards
Ever-tightening automotive fuel emission standards are becoming challenging. The gasoline engine needs the help of an electric motor to meet these standards, leading to the introduction of mild hybrid electric vehicles (MHEV) with higher battery voltages. 48V hybrids are in production vehicles today and are proliferating. A 48V buck converter with integrated MOSFETs in an advanced CMOS process helps meet these standards by withstanding high-voltage load-dump transients and operating with low EMI, low duty cycles, and high efficiency.

High-Efficiency Boost Converter Extends Wearable Medical Patch Battery Life

 

High-Efficiency Boost Converter Extends Wearable Medical Patch Battery Life
The Internet of Things, combined with low power wireless data transmission protocols, is enabling the continuous and real-time monitoring of patient life signs by means of wearable devices. We reviewe the challenges of powering a wearable medical patch with a small disposable 160mAh zinc-air battery. A typical boost converter that regulates the battery voltage falls short of the five-day operating requirement for wearables. On the other hand, a high-efficiency, low-quiescent boost converter can meet and exceed the requirement of five-day operation.
