Products of the Week: August 19, 2024

Aug. 18, 2024

Here's this week's selection of some of the most interesting new products that have been launched of late.

The PSV-RDAD-65USB 65-W USB-C GaN-based power solution combines Pulsiv OSMIUM technology with an industry-standard QR flyback.

65-W USB-C Power Design Operates at 96% Efficiency

Pulsiv released a reference design claimed as the most efficient. The PSV-RDAD-65USB 65-W, USB-C, GaN-based power solution combines Pulsiv OSMIUM technology with an industry-standard QR flyback. Leveraging highly optimized, ultra-compact magnetics, it represents the first in a series of designs aimed at pushing the boundaries of power conversion by drastically lowering operating temperatures, minimizing losses, and reducing solution size. Demonstrating a significant improvement in thermal performance, it reduces critical component temperatures by more than 30% compared to other designs. At full load, the flyback transformer operates at 33.9°C at 230 V AC and 30.3°C at 265 V above an ambient temperature of 26.1°C.

Pulsiv OSMIUM technology senses AC line voltage and frequency to adjust capacitor charging time, drawing no line current at the AC zero voltage crossing, allowing for a half-active bridge implementation to increase efficiency, especially at low line conditions. The half-active bridge strikes a balance between efficiency, cost, and complexity while enabling 65-W fast charging in space-constrained environments and/or heat-sensitive applications. It supports universal input with efficiency gains of 0.7% at full load from a 115-V AC supply.
