Dual MOSFET Simplifies Synchronous Buck Converter Design

News

Advanced Power Electronics Corp (USA) has announced the new AP6922GMT-HF-3, a space-saving dual MOSFET for synchronous buck converter applications, with both the high-side (control) FET and low-side (synchronous) FET in one single 5 x 6mm PMPAK package.

AP6922GMT-HF-3 is a rugged device combining fast switching, low on-resistance and cost-effectiveness. The control MOSFET (CH-1) has a drain-source voltage rating of 30V, a maximum on-resistance of 8.5mΩ and a continuous drain current rating at 25degC of 15A. The synchronous MOSFET (CH-2) also has a drain-source voltage rating of 30V and a continuous drain current rating at 25degC of 25.7A, with a maximum on-resistance of 3.8mΩ to minimise conduction losses. The reduced parasitic inductances resulting from the short internal conduction paths also contribute to improved performance.
The AP6922GMT-HF-3 is the first in a family of parts at the company aimed at synchronous buck converter designs, improving the power density and simplifying the layout.
