Efficiency boost for budget IGBTs
New devices allow designers to use robust low-cost IGBT technology in energy-sensitive circuits such as lighting ballasts operating well above 20kHz.
The latest IGBTs from STMicroelectronics use innovative and efficient lifetime-control techniques to reduce energy loss during turn off New devices, including the STGxL6NC60D 600V PowerMesh IGBT, allow designers to use robust low-cost IGBT technology in energy-sensitive circuits such as lighting ballasts operating well above 20kHz, achieving greater overall efficiency than standard-technology MOSFETs

Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
Single-chip tuner cuts set-top box parts count
The STB6000 single-chip silicon tuner is designed to replace complex discrete component tuners in set-top boxes used for receiving digital TV or web-based material via satellite.
The improvements in switching performance also allow designers to use IGBTs highly competitive designs with hard-switching topologies as well as with resonant circuits.
In addition, the lower turn-off energy allows the device to operate at low junction temperature with a small snubber capacitor, leading to greater benefits including reduced power dissipation, greater reliability and a smaller footprint.
Compared with conventional MOSFETs, ST's new IGBT technology delivers significantly better performance per die area, to enable a reduced-cost solution.
As a further benefit, a copackaged ultrafast soft-recovery diode ensures high dV/dt immunity not achievable with other power devices.
Applications for this new range of hyper-fast IGBTs include high-frequency lighting ballasts from 70 to 150W, as well as switched-mode power supplies, power-factor controllers and other high-frequency power-switching applications.
The four devices that make up the STGxL6NC60D series provide a choice of power packages, with TO-220, TO-220FP, DPAK and D2PAK options.
Prices start at US $0.35 for the STGPL6NC60D in the TO-220 package, for orders over five million pieces.
