Designs requiring the highest quality and enhanced protection features benefit from Infineon's which go beyond AEC-Q101 industry standards providing the most reliable MOSFETs in the industry. Designers benefit from the ultra-low switching losses of the technology in applications above 100kHz in power supply applications as well as the highly robust in applications with the need for high avalanche protection such as motor control. DC-DC applications can be classified by their needs for extremely fast switching with low losses or more robust switching at moderate frequencies. An output pin of a microcontroller is usually adequate to drive a small-signal logic level.ĪC-DC applications requiring high voltage blocking capability and fast switching with low losses take advantage of the revolutionary superjunction technology for more efficient power supplies. A MOSFET driver IC translates TTL or CMOS logical signals, to a higher voltage and higher current, with the goal of rapidly and completely switching the gate of a MOSFET. The driver and the input capacitor of the device. The focus of this topic is the gate drive requirements of the power MOSFET in various switch mode power conversion applications.
