Alpha and Omega Semiconductor’s synchronous DC/DC buck regulators achieve up to 6% higher efficiency in standby mode


Alpha and Omega Semiconductor

Alpha and Omega Semiconductor unveiled AOZ6682CI and AOZ6683CI, high efficiency, simple-to-use synchronous buck regulators.

Available in an ultra-thin, thermally enhanced TSOT23-6 package, they 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.”
