Many switch-mode power supplies use “kick-start” circuits to initialize their offline operation. These circuits may be simple resistors, such as International Rectifier’s IRIS4015, or more complicated ...
An engineer once told me that he never looks at the first page of mosfet datasheets since the 'practical' information doesn't begin until page 2. In fact, every page of a mosfet datasheet contains ...
Diodes has introduced the APR348,a secondary-side, multi-mode synchronous rectification MOSFET driver designed for AC-DC rectification circuits in general consumer applications, notebooks, and USB ...
Power MOSFETs are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of ...
Previously [1, 2, 3], several isolated DC-DC converter topologies were analyzed and we showed that eGaN FETs enabled significant efficiency improvements in all cases. Because buck converters, do not ...
Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...
