High Voltage MOSFET is optimised for power supply start-up
A high voltage MOSFET from Zetex Semiconductors has been introduced to handle the requirements of pre-bias supply circuitry. A 450V enhancement mode N-channel device, the ZXMN0545G4 is used in a simple linear regulator to supply PWM ICs at start-up, and is disabled once the converter is fully on.
Current monitor enables true short circuit current monitoring
With its wide common mode sense range of 0V to within 2V of the supply voltage applied, the ZXCT1051 current monitor from Zetex Semiconductors enables true short circuit current monitoring.
Miniature bipolar package increases power supply efficiency
Combining complementary NPN and PNP transistors in the SOT236 package, the ZXTC2045E6 from Zetex Semiconductors produces the drive requirement needed to switch high power MOSFETs and IGBTs in power supply designs.
Voltage regulator powers next-generation graphics processing units
Intersil's latest single-phase buck voltage regulator is designed to power next-generation graphics processing units (GPUs) or graphics cores used on Intel Santa Rosa platforms. The device reduces power consumption and enhances the performance of the GPU by dynamically changing output voltage and operation modes corresponding to the advanced GPU control protocol.
175W AC/DC switcher delivers any required voltage on each of four outputs
