42. E-fuses: warming up to higher-current applications
    Bill Schweber
    Supply Texas Instruments TPS25925 TPS25926
    As a cautious analog-centric engineer, I have always liked traditional thermal-based fuses and been somewhat skeptical of electronic fuses (also written as e-fuses or eFuses) due to their active components. After all, when it comes to reliability, ...

43. Cascode Configuration Removes Miller Effect, Boosts PFC Performance
    Gregory Mirsky
    Supply Texas Instruments LM78L15 UC3854AN
    The power factor corrector (PFC) front end of an off-line power supply is subject to the operating frequency limitation caused by the Miller Effect of its associated power MOSFET. This effect is a property of any transistor configuration with a ...
