Synchronous DC/DC Buck Regulators Feature Lower
Quiescent Current and Proprietary Light load Mode to Achieve up to
6% Higher Efficiency in Standby Mode
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 introduced AOZ6682CI and
AOZ6683CI. These devices are high efficiency, simple-to-use
synchronous buck regulators. The AOZ6682CI and AOZ6683CI are both
available in an ultra-thin, thermally enhanced TSOT23-6 package and
deliver 2A and 3A output current, respectively. The new devices
offer high efficiency over the full load range, allowing greener
power conversion for a variety of consumer electronics applications
such as LCD TVs, set-top boxes, high definition Blu-rayTM Disc
Players and Networking terminals.

The new devices incorporate a low resistance synchronous buck
power stage that enables up to 95% efficiency. Combined with a
thermally enhanced package, the AOZ6682CI and AOZ6683CI achieve
10°C cooler operation at full load compared to similar competing
devices. Under heavy load conditions, the devices operate in a
fixed frequency continuous-conduction mode (CCM). At light loads or
in standby mode, the devices employ a proprietary pulse energy mode
(PEM) control scheme. This control scheme and low quiescent current
of 200uA, allows the buck converter design to achieve
industry-leading efficiencies of 89% at light loads.
“Modern consumer equipment must achieve less than 0.5W in
standby power consumption and this is a tough problem for system
designers to solve,” said Kenny Hu, Power IC Marketing Manager at
AOS. “The newest 2A and 3A additions to the EZBuck family simplify
this task, offering up to 6% improved efficiency compared to
competing devices thanks to low quiescent current and a proprietary
power-saving light load control scheme.”
