WebThe switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding). WebReducing ringing A test circuit with a 1.1-V/20-A buck con-verter was used to show the effects of switch-node ringing. This circuit used the TI TPS40304 600-kHz buck control-ler and the CSD87350Q5D fast-switching NexFET™ power block. The input-voltage range was 8 to 16 V. As a baseline reference, a switch-node waveform (Figure 2) and

Web3 Trapezoid Rule The Trapezoid Rule is a closed Quadrature rule where f(x) is only evalu-ated at the endpoints aand bon the inter-val [a;b]. Visually on a graph, we see the line that passes through points (a;f(a)) and (b;f(b)), which forms a trapezoid with the x-axis. Thus, the area under the curve can be approximated by the area a Trapezoid, as
