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 while minimizing acoustic noise. To ensure light load performance with high frequency designs, the NCP1342 incorporates Rapid Frequency Foldback with Minimum Peak Current Modulation to reduce the switching frequency quickly. To help ensure converter ruggedness, the NCP1342 implements several key protective features su.
