New devices in the vendor's Gen III TrenchFET power-MOSFET line include two 20V and two 30V N-channel devices. The units have a 76.6-mΩ-nC on-resistance×gate-charge figure of merit of 4.5V and a 117.6.-mΩ-nC on-resistance-×gate-charge figure of merit of 10V. A high-side MOSFET in synchronous-buck converters saves power in notebook computers, VRMs (voltage-regulator modules), servers, and other systems using POL power conversion. The vendor claims a 45% gate-charge reduction using TurboFET technology with a charge-balanced drain structure, enabling lower switching losses and faster switching. The Gen III Trench-FETs are available in PowerPak 1212-8 and PowerPak SO-8 packages, and prices start at 32 cents (100,000).
