Power MOSFET from STMicroelectronics makes lighting more efficient
STMicroelectronics has introduced the first member of a new power MOSFET family. The new family allows customers to drastically reduce conduction losses and increase efficiency and reliability of their lighting applications by achieving very low ON-resistance and excellent dynamic and avalanche characteristics.
TI Introduces DC/DC Power Module for 3-GHz DSP Systems
Texas Instruments has introduced a 10A, non-isolated DC/DC power module with fast transient response and high performance. The plug-in module meets the strict three percent accuracy core voltage tolerance requirements of TI's newest 3-GHz digital signal processors (DSPs), such as the TMS320TCI6487, with only 3,000 µF of external output capacitance. The device also supports point-of-load systems that use high-performance DSPs, microprocessor...
Synchronous buck-boost DC/DC converter drives two banks of white LEDs
Linear Technology has announced the LTC3452, a synchronous buck-boost DC/DC converter optimized for driving two banks of white LEDs from a single Li-Ion battery. Up to five parallel LEDs can be driven at up to 25mA each for backlighting LCD panels, while two LEDS can be driven at up to 200mA each (or one LED at 400mA) for camera flash applications. The LTC3452's synchronous buck-boost topology delivers up to 90% efficiency over the entire usable ...
