Start with the news release Linear introduces H-grade switching regulator from Linear Technology, which we summarised at the time by saying "Linear Technology has announced a H-grade step-down switching regulator for load dump and cold-crank conditions commonly found in automotive applications as well as 24V industrial supplies.". Several months prior to that, we featured the news release Power-management controller for standard MOSFETs from Texas Instruments: "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. ".
 
In December 2010, we covered the news from Linear Technology - take a look at Compact linear regulator with thermal resistance which says: "Linear Technology has produced a wider-temperature-range version of the LT3010, a high-voltage, micropower linear regulator for avionics, military, industrial, automotive, RF and telecom applications.".
 
Take a look also at the news release from Allegro Microsystems, Sensor IC withstands harsh automotive environments, as well as Driver controller for illumination and signage from Diodes Incorporated, and Current mode controllers for military applications from Linear Technology.
