Low Voltage ICs Discretes: OptiMOS , OptiMOS 2 Power Management & Supply: DC/DC Selection Guide www.infineon.com/power Never stop thinking.Introduction DC/DC CONVERSION plays a critical role in todays applications such as desktop and notebook computers, consumer equipment e.g. DVD players and set-top boxes or portable electronics, such as PDAs, MP3 players to mention but a few. ALL THESE APPLICATIONS make ever-increasing demands on the internal power conversion power losses must be reduced and efficiency improved, translating into less heat and a longer battery lifetime. At the same time devices are constantly shrinking in size, increasing the power density. WE CAN HELP you out. Our OptiMOS 2 power MOSFET technology reduces the resistive and switching loss components significantly. The gate charge and consequently the figure-of-merit of our devices has become the new industry benchmark. More importantly, the output charge is reduced to extremely low levels, minimizing the total switching losses for a given output current. At the same time, best-in-class power MOSFETs with an on-resistance in the range of 3 m and below, are now possible, making new circuit con- cepts and applications possible. New packages like our SSO8 show strongly reduced package resistances, and furthermore parasitic inductances. Coupled with excellent thermal performance, our new 30 V OptiMOS 2 pro- ducts allow for new levels of power conversion efficiency especially in portable applications. For applications with space constraints, a large product portfolio of devices in smaller packages is available, including dual and complementary devices. c c d s IN A DC/DC CONVERTER solution all components must be optimized in order to achieve the highest efficiency and power density, at a given cost. Our low-voltage control ICs and gate drivers are designed for optimum performance, along with new ideas for control and protection functions. 2
