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 Compact linear regulator with thermal resistance from Linear Technology, and Voltage controller with integrated power MOSFET from Linear Technology.

TPS54618 for DSP- and FPGA-based communications (December 2010)
The TPS54618 provides 95-per-cent efficiency and operating current of 2.95-6V for point-of-load designs used in DSP- and FPGA-based communications, test and medical equipment.
PFC/PWM controller targets power engineers (December 2010)
Fairchild Semiconductor is offering the FAN6920MR, an integrated critical mode PFC and quasi-resonant current-mode PWM controller.
- Ceramic varistor exhibits low leakage current
AVX has expanded its zinc oxide (ZnO) based varistor series to include an 18V-rated version that exhibits a low leakage current of 1uA maximum, which extends battery life in portable devices.
Varistors have very low leakage currents
Ideal for transient protection applications where power consumption is a primary concern.
