Overview

Texas Instruments' synchronous MOSFET half bridge achieves greater than 90% efficiency at 25A and in half the area of competitive power MOSFET devices. The CSD86350Q5D power block combines two asymmetric NexFET power MOSFETs in an advanced package that delivers high performance in low-voltage synchronous buck half-bridge applications, including servers, desktop and notebook PCs, base stations, switches, routers, and high-current point-of-load (POL) converters.

In addition to improving efficiency and power density, the NexFET power block can generate up to 40A of current with a switching frequency of up to 1.5MHz, which reduces solution size and cost. The optimized pinout and grounded lead frame significantly reduces development time and improves overall circuit performance. Furthermore, the NexFET Power Block can achieve comparable performance to other semiconductor technologies, such as GaN, but in a cost-effective manner.
