NCP1271ADAPGEVB 19 V, 3.0 A Universal Input AC-DC Adaptor Using NCP1271 Evaluation Board
... The NCP1271 includes a current sense (CS) Leading Edge Blanking (LEB) filter. The LEB filter blanks out the first 180 ns (typ) of the CS voltage at the beginning of each drive pulse. This helps to prevent a premature reset of the output due to noise. However, this also results in a minimum on time o ...

Power MOSFET
A power MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle significant power levels.Compared to the other power semiconductor devices, for example an insulated-gate bipolar transistor (IGBT) or a thyristor, its main advantages are high commutation speed and good efficiency at low voltages. It shares with the IGBT an isolated gate that makes it easy to drive. They can be subject to low gain, sometimes to degree that the gate voltage needs to be higher than the voltage under control.The design of power MOSFETs was made possible by the evolution of CMOS technology, developed for manufacturing integrated circuits in the late 1970s. The power MOSFET shares its operating principle with its low-power counterpart, the lateral MOSFET.The power MOSFET is the most widely used low-voltage (that is, less than 200 V) switch. It can be found in most power supplies, DC to DC converters, and low voltage motor controllers.
