STMicroelectronics has introduced NEATSwitch, a portfolio of application-specific analog, digital and power switches. Demand is driven by the continuing rapid convergence of functions in mobile and digital consumer equipment. Another driver is the...
Device junction temperature and other operating
conditions are critical in determining
the avalanche current capability and forward
bias safe operating area for MOSFETs
designed in different processes.
Using a new version of power MOSFET figure of
merit and constant-power dissipation curves,
designers can calculate the optimum combination
of factors to select a device for a power supply
application and minimize its dissipation.
Even if small, a transformer’s leakage inductance reduces the efficiency of some isolated dc-dc converter topologies. However, the technique of lossless voltage clamping helps restore most of the lost energy.
