?Current Transducers?

An Electronicstalk guide

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 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 Bear Power Supplies, AC/DC power converters for medical applications, as well as Transducers suited to shock and vibration tests from RDP Electronics, and Compact linear regulator with thermal resistance from Linear Technology.
