Infineon is the market leader in highly efficient solutions for power generation, power supply and power consumption. The latest generation of Infineon’s MOSFET transistors were designed to ensure market leading performance, improve efficiency and to achieve better thermals in terms of the state of the art EMI behavior.
AC-DC applications requiring high-voltage blocking capability and fast switching with low losses take advantage of the revolutionary CoolMOS™ superjunction technology for more efficient power supplies. Infineon’s superjunction MOSFETs serve today's and especially tomorrow’s trends in different topologies, ranging from a simple flyback to TCM Totem Pole PFC. Designers benefit from a lower temperature, the improved form factor, and increased efficiency.
Rudy described how Hexfets could do wonderful things for switch-mode power supplies, but he quite pointedly suggested that they might be a troublesome choice for making a linear amplifier, or for use in any other non-saturating service. There were two issues. High current redundant power supply using ORing MOSFET controllers Selecting Power FETs Selecting the right power FET is necessary to help the ORing MOSFET controller perform its job. You can select a suitable FET by following these steps: 1) Use an N-channel FET that has a drain-source voltage (Vds) breakdown that is greater than the bus.
Many of the most common power MOSFET applications involve devices, in either half- or full-bridge configurations, driving inductive loads. Buck-converter topologies are a typical example. The high-side FET operates with a duty cycle D approximately equal to A typical buck converter topology. Broadcom RF and microwave devices have been driving the wireless revolution with products including amplifiers, FBAR filters, multipliers, switches, and embedded processors.
