DC/DC regulators offer 90% peak efficiency

Keywords:AOS  EZBuck  DC/DC regulators 

Alpha and Omega Semiconductor Inc. announced the expansion of its power management solutions by releasing a brand new family of DC/DC regulators. The EZBuck family of regulators is aimed at applications such as portable DVD players, digital STBs, flat panel displays and TVs, wireless access points, low-cost PCs, communications equipment and general purpose point-of-load DC/DC conversion applications.

The new regulators take advantage of the company's unique combination of Power IC MOSFET and packaging technologies to achieve new levels of performance, integration and ease-of-use, AOS said. These fixed frequency PWM regulators promise a peak efficiency of at least 90 per cent at rated load current. The high efficiency is achieved by optimising a control stage to drive a low Rds(on) power stage comprised of the company's proprietary Trench MOSFET technology. Accepting an input voltage from 4.5V to 16V, the new regulators are suitable for applications that use a 5V or 12V nominal input voltage. Also available are devices that provide output current from 1.5A up to 5A in a single 8-pin package, thereby offering customers a rich choice of solutions for their applications, AOS said. Additional features include integrated soft-start, integrated Schottky diode options, over-current and thermal protection and programmable output voltage down to 0.8V.

The AOZ1010AI, AOZ1012DI, AOZ1013AI and AOZ1014AI/DI are already available. Samples are available from stock with production quantities available in eight weeks. Pricing starts at Rs.26.94 (58 cents) each for 1,000 units.
