Alpha and Omega Semiconductor Debuts New Smart EZBuck Regulator Featuring Adaptable Light Load with Surge Output Current Capability

 Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today announced the release of the AOZ3053, a 5A EZBuck DC/DC regulator with smart mode adaption functions, available in a thermally enhanced exposed pad SO-8 package. The AOZ3053 is the first of this new smart platform, which allows for more thermally efficient DC/DC solutions for consumer, networking and industrial applications such as LCD TVs, set-top boxes, cable modems, and power supplies. The AOZ3053 is a high efficiency and simple-to-use synchronous step-down regulator with PWM switching frequency of 500kHz and input voltage range of 4.5V to 18V. Leveraging AOS’s co-package EZBuck design, the AOZ3053 integrates a 55m high-side and 15m low-side MOSFET, and provides 5A of continuous output current at over 90% efficiency and maintains it at 85% efficiency while in 10mA light load operation. This new device offers various features such as adaptable light load with surge output current capability, over-voltage protection, cycle-by-cycle current limit and short-circuit protection which are a must when powering high-end digital ICs. “Today’s consumer electronics products are built with features that require more processing power. Design engineers are looking for DC/DC converters that offer higher output current in the same solution size while minimizing power consumption with high-efficient, high-performance power conversion. The AOZ3053 meets these design challenges by providing higher output current and higher efficiency,” said Kenny Hu, Power IC Marketing at AOS.
