Alpha and Omega Semiconductor Launches 5A EZBuck DC-DC Regulator with Ultra Pulse Energy Mode (U-PEM)
Alpha and Omega » AOZ6605
New synchronous buck regulator with enhanced light load efficiency and lower output voltage
Alpha and Omega Semiconductor (AOS) announced the release of the AOZ6605, a high efficiency and simple-to-use synchronous step-down regulator with PWM switching frequency of 650 kHz and input voltage range of 4.5 V to 18 V. The solution is ideal for consumer, networking and industrial applications such as LCD TVs, set-top boxes, cable modems, and power supplies.
Leveraging AOS's co-package EZBuck™ design, the AOZ6605 integrates a 55 mΩ high-side and 12 mΩ low-side MOSFET, and provides 5 A of continuous output current at over 90% efficiency and maintains it at 86% efficiency while in 10 mA light load operation.
When operating in low output current conditions, the AOZ6605 will operate in an ultra pulse energy mode (U-PEM) to obtain high efficiency. Under heavy load steady-state conditions, the AOZ6605 will operate in fixed frequency and Continuous-Conduction Mode (CCM).
