Integrated Load Switches versus Discrete MOSFETs
Alek Kaknevicius @ ti.com discuss about load switches and the advantages of intergrated switches over discrete ones. The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully...
