Layout Considerations
As in any high frequency switching converter, layout is
very important. Switching current from one power device to
V IN
another can generate voltage transients across the
impedances of the interconnecting bond wires and circuit
traces. These interconnecting impedances should be
minimized by using wide, short printed circuit traces. The

possible using ground plane construction or single point

grounding. Figure 17 shows the critical power components
of the converter. To minimize the voltage overshoot the
GND
interconnecting wires indicated by heavy lines should be
part of ground or power plane in a printed circuit board. The
components shown in Figure 17 should be located as close
together as possible. Please note that the capacitors C IN and
C OUT each represent numerous physical capacitors. It is
desirable to locate the NCP1580 within 1 inch of the
MOSFETs, Q1 and Q2. The circuit traces for the MOSFETs’
gate and source connections from the NCP1580 must be
sized to handle up to 2.0 A peak current.
