‘Pwm Controllers’
An Electronicstalk guide
Start with the news release Voltage controller with integrated power MOSFET from Linear Technology, which we summarised at the time by saying "Linear Technology has introduced the LTC4219 5A Hot Swap controller with sense resistor, for protecting low-power boards from inrush current in many RAID, server, telecom and industrial applications.". Several months prior to that, we featured the news release Current mode controllers for military applications from Linear Technology: "Military-temperature-grade versions of the LTC3803/-3/-5 current mode flyback controllers are available in a six-pin ThinSOT package for industrial, telecom, military and automotive applications.".
In December 2010, we covered the news from Avalue Technology - take a look at TFT touch-panel PC for POS/kiosk applications which says: "Avalue Technology has introduced the FPC-08W05, an 8.9in WSVGA TFT touch-panel PC that can be wall mounted or integrated as an HMI, food service panel PC or POS/kiosk display system.".
Take a look also at the news release from Molex, Connector system for engine control units and more, as well as Oscillator for PCIe-based embedded applications from MSC Vertriebs, and RAID controllers for high I/O transaction apps from PMC-Sierra.
