‘Trench Mosfets’
An Electronicstalk guide
Start with the news release International Rectifier offers automotive MOSFETs from International Rectifier, which we summarised at the time by saying "International Rectifier has expanded its offering of 40 to 100V automotive-qualified MOSFETs, including a range of logic level devices. ". Several months prior to that, we featured the news release Self-protected MOSFETs for automotive applications from Diodes Incorporated: "Suiting automotive and industrial applications, Diodes Incorporated's new self-protected MOSFETs are suitable for switching inductive loads, such as motors, relays and lamps at low frequencies. ".
In December 2010, we covered the news from Texas Instruments - take a look at Power-management controller for standard MOSFETs which says: "Texas Instruments has introduced a power-management controller and driver for standard and logic-level N-channel MOSFETs used for low-voltage, secondary-side synchronous rectification. ".
Take a look also at the news release from Linear Technology, DC/DC uModule PoL regulator for RAID systems, as well as 100V MOSFETs launched for space applications from International Rectifier, and Synchronous buck regulator for POL applications from Semtech.
