This product associates the latest low voltage StripFET] in n-channel version to a low drop Schottky diode. Such configuration is extremely versatile in implementing, a large variety of DCDC converters for printers, portable equipment, and cellular phones.
This application specific Power Mosfet is the third generation of STMicroelectronics unique "Single Feature Size]" strip-based process. The resulting transistor shows the best trade-off between on-resistance and gate charge. When used as high and low side in buck regulators, it gives the best performance in terms of both conductionand switching losses. This is extremely important for motherboards where fast switching and high efficiency are of paramount importance.
