Alpha and Omega Semiconductor Limited (AOS) has launched AOZ3015, a 3A EZBuck DC/DC regulator optimized for applications that have a standby power mode.
According to the company, AOZ3015 is a high-efficiency, easy-to-use 3A synchronous buck regulator that works from 4.5 V to 18 V input voltage range, and provides up to 3A of continuous output current with an output voltage adjustable down to 0.8 V.
This solution can be used with point-of-load DC/DC converters, LCD TVs, set-top boxes, DVD and Blu-Ray players/recorders and cable modems.
The AOZ3015PI comes in an exposed pad SO-8 package and is rated over a -40 °C to 85 °C operating ambient temperature range, providing 3A of continuous output current at over 90 percent efficiency.
The regulator maintains 85 percent efficiency while in 10mA light load operation.
This new product also works with in low-output current conditions, and in a proprietary pulse energy mode (PEM) to obtain its high efficiency. Under heavy load steady-state conditions, the AOZ3015 will operate in fixed frequency and Continuous-Conduction Mode (CCM (News - Alert)).
"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."
The AOZ3015 is currently available in production quantities within 12 weeks of a request. The unit price for 1,000 pieces is $0.80.
