AO4294 utilizes AOS’s leading process technology to generate a very low on-resistance when working as the secondary-side rectifier of an ac-dc converter. The AO4294 is available in the standard SO-8 package, which gives lower-output power supply designers the convenience of an easy-to-use and cost-effective PCB design. Additionally, this device allows the possibility of an even smaller circuit form factor, due to extremely low switching losses.

“The ever growing application base for contemporary smart phones is driving the demand for higher battery capacity. At the same time, the ability to charge up the battery faster and more efficiently is becoming critical for smart phone users. This has led AOS to work with leading quick charger designers to provide the best performing MOSFETs for secondary-side rectification to achieve the highest efficiency.” said Lei Feng, Director of Market Development for the MOSFET product line at AOS. “As one of the best performing parts in the 100V category, the AO4294 will help our customers significantly in designing efficient charger circuits with higher reliability as the benefit of extremely low on-resistance.”
