Renesas Electronics has announced the development of the RJK0222DNS and RJK0223DNS, two power semiconductor devices with ultra-compact packages for use in DC/DC converters  that provide power to the MCU/CPU, memory, and other circuit blocks of products such as servers and notebook PCs.

The new power semiconductor products each integrate a pair of power MOSFETs into a single package, enabling designs of DC/DC converters that are more compact with higher mounting density. The compact, low-loss 11th generation power MOSFETs, fabricated using an advanced process,  are contained in an ultra-compact package measuring only 3.2 millimeters (mm) × 4.8 mm × 0.8 mm (max.), making it possible to reduce the mounting area by about half compared with previous Renesas Electronics power MOSFET products, and deliver efficiency of 95.2 percent, the top level in the industry, which contributes to reduced power consumption.

Information and telecommunication devices such as base stations, notebook PCs, servers, and graphics cards require multiple step-down DC/DC converters because they incorporate components, such as CPUs, GPUs, memory devices, and ASICs, that require a power supply voltage lower than that supplied by the battery. As demand grows for information devices that are smaller and more streamlined, so the need grows for DC/DC converters that are more compact, thinner, and more highly efficient.

In response to this demand, Renesas Electronics has developed the two power devices, each of which integrates a pair of power MOSFETs in an ultra-compact package. The designs benefit from the company’s expertise in smaller package development and higher heat-radiation packages developed through Renesas Electronics’ ultrafine power MOSFET technology.

Renesas Electronics plans to develop a full lineup of dual-chip products using the HWSON3046 package for a variety of DC/DC converter specifications.
