Alpha and Omega Semiconductor Ltd. (AOS) recently announced the release of AO4294, the latest addition to AOS's family of high efficiency charging solutions. This new device is offered in an easy-to-use SO-8 package, which helps manufacturers keep the mounting cost low, while still getting the best efficiency and power dissipation possible. The AO4294 is an ideal solution for synchronous rectification in high efficiency chargers and adapters for mobile devices.
AO4294 utilizes AOS's 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 AO4294 is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 1,000 pieces is $0.60.
