OptiMOS 5 25V and 30V Product Family Exceeds 95% Efficiency

March 17, 2015
Infineon Technologies AG 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 5x5.

Infineon Technologies AG 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 5x5. 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. This improved performance is based for example on the reduction of switching losses (Q switch) by 50 percent compared to the previous OptiMOS technology. Thus, implementing the new OptiMOS 25V would lead to energy savings of 26.3kWh per year for a single 130W server CPU working 365 days. Adding 50.000 servers working in a server farm on average this would amount to savings of 1.3GWh per year.

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 5x5 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 5.0x6.0mm 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 5x5, 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°C (compared to ±10°C of an external one) which enables higher system reliability and performance.
