Texas Instruments’ CSD86350Q5D Power Block consists of two asymmetric NexFET power MOSFETs with advanced packaging technology 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 converters. In addition to desirable efficiency and power density, the NexFET Power Block can generate up to 40 A of current and achieve higher switching frequency, which helps further reduce solution size and cost. The device can also switch at twice the frequency of competitor’s power MOSFET devices, according to the company. Furthermore, the optimized pinout and grounded leadframe reduces development time and improves overall circuit performance. The company asserts the CSD86350Q5D Power Block offers wo percent higher efficiency when operating in a synchronous buck circuit at 25 A, which results in an energy-efficient point-of-load design, and it is said to offer double the frequency without increasing power loss versus competitive solutions.
