What’s New Powermosfets optimise efficiency
by a battery to 1.05V for use by the CPU. The new mosfets also achieve approximately 40 per cent lower figure ofmerit (FOM) compared to the company’s existing products, reducing power loss during voltage conversion and thereby enabling efficient DC/DC converter performance.
As the performance of applications such as
Renesas Electronics has announced its new 12th- generation powermosfet products, the RJK0210DPA, RJK0211DPA and RJK0212DPA power semiconductor devices for DC/DC converters used in applications such as general point-of-load, base stations, computer servers and notebook PCs.
The products are used to control the voltage-
conversion circuits of CPU andmemory devices. For example, the new powermosfets can be used as a step-down circuit for converting the 12V supplied
Serving up what consumers really want

EAO is offering a new spring terminal connector technology for its series 04 switch range. The series 04 push-in terminal (PIT), which features a spring terminal connection fromPhoenix Contact, is said to reduce assembly times by up to 70 per cent compared to screw terminals. It claims to offer amore reliable, secure connection in combination with a high resistance to vibration,making it ideal for transportation,mechanical engineering and process automation.
Moreover, the cable connection is accomplished without
tools. The stripped wire-end is pushed into the spring terminal, which applies the correct pressure tomaintain a secure connection over the lifetime of the switch. Depending on the application, not even core-end sleeves are needed. PIT offers protection against contact according to IP20.
The EAO series 04 has been upgraded with the following three
products with push in terminal technology: a snap-action switch element, a slow-make element and a lamp block. Elements are stackable, for up to six contacts per switch.
The push-in terminals connect to any of the series 04 actuators,
including square and round pushbutton versions, two-or-three position lever switches, key lock switches, emergency-stops and large-headed buttons. Series 04 equipment offers front protection to IP65, is rated 500VAC and operating temperature is -25 to 55°C.

servers, notebook PCs and graphics cards increases, their power consumption grows.Meanwhile the trend toward lower operating voltages for components such as CPUs, graphics processing units (GPUs),memory, devices and ASICs results in increased current flow. This creates a need for DC/DC converters capable of handling low voltages and large currents. There is also strong demand for reduced power loss during voltage conversion and higher efficiency to help conserve energy and reduce environmental impact. Renesas Electronics claims to address these demands with its expanding line of low-FOMpowermosfet products.
