SUNNYVALE, CA –
Alpha and Omega Semiconductor Limited , a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today released the AOZ3015, a 3A EZBuck DC/DC regulator optimized for applications that have a standby power mode. The AOZ3015 is ideally suited for point-of-load DC/DC converters, LCD TVs, set-top boxes, DVD and Blu-ray players/recorders and cable modems.
The AOZ3015 is a high-efficiency and easy-to-use synchronous PWM buck regulator with an input voltage range of 4.5V to 18V. It provides 3A of continuous output current at over 90% efficiency and maintains 85% efficiency while in 10mA light load operation. When operating in low output current conditions, the AOZ3015 will operate in a proprietary pulse energy mode (PEM) to obtain high efficiency. Under heavy load steady-state conditions, the AOZ3015 will operate in fixed frequency and Continuous-Conduction Mode (CCM).
“AOS’s proprietary EZBuck technology helps bring our customers compact and high efficiency DC/DC solutions that we can scale to their power requirements.” said Dr. Yenju Wang, Product Marketing Director at AOS. “The high-efficiency light load operation feature AOZ3015 makes it an ideal for those power supplies with a stand-by mode mandated by many government agencies worldwide.”
