SUNNYVALE, Calif., Nov. 6, 2014 (GLOBE NEWSWIRE) -- 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 fifth generation EZBuck™ with the AOZ3103, a high efficiency, simple-to-use synchronous buck regulator, with an operating input voltage range from 4.5V to 18V and the ability to supply 3A of continuous current. The device offers a low on-resistance power stage in a thermally enhanced 3mm x 3mm DFN package, allowing cooler power conversion for a variety of consumer electronics applications such as LCD TVs, set-top-boxes, as well as DVD players and recorders.

The AOZ3103 is a current-mode step-down regulator with integrated high-side and low-side NMOS switches. The device features external compensation for added design flexibility, and to improve performance in low duty cycle applications. Compared to the leading competitor, the AOZ3103's input voltage rating is 2V higher and its feedback tolerance is 0.5% tighter, which allows for greater safety design margin as well as a higher degree of output voltage accuracy. The device also features a Power-On Reset (POR), input under-voltage lockout and output over-voltage protection.
"The AOZ3103 provides an ideal 3A DC-DC buck regulator solution for a wide variety of space-constrained applications," said Kenny Hu, Power IC Product Marketing at AOS. "It's wider safety margin, cooler operation, and higher output voltage accuracy helps to simplify the system power design for our customers."
