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 Fairchild offers USB-compliant switching chargers from Fairchild Semiconductor: "Fairchild Semiconductor has developed the FAN5400 series of USB-compliant, Lithium-ion switching chargers with USB On-The-Go (USB-OTG) capabilities for smart phones, tablets and digital cameras.".

In November 2010, we covered the news from ZMD - take a look at Low-voltage ICs for mobile phone and GPS backlight which says: " ZMD has introduced two new ZLED low-voltage ICs, incorporating low-noise, constant-frequency charge pump DC/DC converters that can drive up to four (ZLED7012) or six (ZLED7022) strings of LEDs.".

Take a look also at the news release from Linear Technology, DC/DC controller targets ASIC and FPGA supplies, as well as Analogue timer for small electrical appliances from Semtech, and Power-management circuits for portable electronics from Texas Instruments.
