NCP1342 Features

* a proprietary valley

* lockout circuitry, ensuring stable valley switching. This system works down to the 6th valley and transitions to frequency foldback mode to reduce switching losses. As the load decreases further, the NCP1342 enters quiet

* skip mode to manage the power delivery whi
