AOZ6682/3CI – High Efficiency Synchronous Buck Regulators with Low Quiescent Current for Consumer Electronics Applications
![AOZ6682CI Synchronous Buck Regulator](/sites/default/files/components/AOZ6682CI-Synchronous-Buck-Regulator.jpg)
Alpha and Omega Semiconductors have introduced 18V, 2A and 3A high efficiency, simple to use synchronous buck regulators namely AOZ6682CI and AOZ6683CI. Both the devices are available in an ultra-thin thermally enhanced TSOT23-6 package and they 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-ray Disc Players and Networking terminals.
AOZ6682CI and AOZ6683CI are designed with a low resistance synchronous buck power stage that enables up to 95% efficiency. As they are thermally enhanced, they achieve 10°C cooler operation at full load compared to similar competing devices. When the device is operating under heavy load, they operates at 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.
