en.Wedoany.com Reported - Alpha and Omega Semiconductor (AOS) recently announced the launch of its SmartClamp protected DrMOS series in the United States, specifically designed for AI servers, data centers, and high-end graphics cards. This series offers high-precision Over-Current Protection (OCP) and Negative Current Protection (NCP), with its flagship product, the AOZ53228QI, preventing failures in multi-phase voltage regulators under high peak currents.

In AI applications, peak currents often exceed the limits of standard devices. Traditional protection methods have delays; even a 50ns OCP delay can cause a 30A current runaway, damaging the MOSFET. The SmartClamp DrMOS series eliminates this risk by directly limiting the current within the power stage, avoiding reliance on the controller. Technical highlights include cycle-by-cycle monitoring, precise forward and reverse current limiting, and compatibility with various PWM controllers.

Zach Zhang, Marketing Director for Power ICs at AOS, stated: "AOS designed the SmartClamp DrMOS series to address the specific 'stress tests' of modern AI workloads. By pairing these with our advanced controllers, we offer an efficient Vcore solution that gives designers peace of mind in high-density power applications."

AOS is a global power semiconductor supplier, with products covering discrete devices, power management ICs, and more, serving applications in personal computers, data centers, AI servers, and other fields.
