Infineon Technologies AG today introduced the OptiMOS™ 5 25V and 30V product family, the next generation of power MOSFETs in standard discrete packages, a new class of power stages named Power Block, and in an integrated power stage, DrMOS 5×5. Together with Infineon’s driver and digital controller products the company delivers full system solutions for applications such as server, client, datacom or telecom.

Megatrends such as cloud computing, Internet of things and social media drive an ever increasing demand for computing power in modern society. This is accompanied by a boost in energy consumption which, in return, triggers the need for energy efficiency within the power conversion chain. The newly-introduced OptiMOS 25V and 30V product family offers benchmark solutions with efficiency improvements of around 1 percent across the whole load range compared to its previous generation, exceeding 95 percent peak efficiency in a typical server voltage regulator design.

The launch of the OptiMOS 25V and 30V product family is accompanied by the introduction of a new packaging technology offering a further reduction in PCB area consumption. It is used in the Power Block product family and in the integrated powerstage DrMOS 5×5 and offers a source down low-side MOSFET for improved thermal performance, with a reduction by 50 percent of the thermal resistance in comparison to standard package solution, such as SuperSO8.
Infineon`s Power Block is a leadless SMD package comprising the low-side and high-side MOSFET of a synchronous dc-dc converter into a 5.0×6.0mm 2 package outline. With Power Block, customers can shrink their designs up to 85 percent by replacing two separate discrete packages, such as SuperSO8 or SO-8. Both, the small package outline and the interconnection of the two MOSFETs within the package minimize the loop inductance for best system performance.

OptiMOS 5 25V is also used in an integrated power stage, combining DrMOS 5×5, driver and two MOSFETs, for a total area consumption on the PCB equal to 25mm². The integrated driver plus MOSFETs solution results in a shorter design time and is easy to design-in. Additionally, the dovetailed power stage includes a high accurate temperature sense of +/-5 degrees C (compared to +/-10 degrees C of an external one) which enables higher system reliability and performance.
“With the significant reduction in switching losses, the OptiMOS 5 products allow engineers to operate their designs at higher switching frequencies, reduce energy consumption and save overall system costs. Together with our digital IC and driver family we offer a broad range of complete solutions for dc-dc voltage regulation applications, where DrMOS 5×5 and Power Block products are the designers` choice for highest efficiency in industry standard footprints,” stated Richard Kuncic, Vice President and General Manager Power Management & Multimarket at Infineon Technologies.
