Figure 5 shows the critical power components of the converter.
To minimize the voltage overshoot the interconnecting wires
indicated by heavy lines should be part of ground or power
plane in a printed circuit board. The components shown in
Figure 5 should be located as close together as possible.
Please note that the capacitors C
numerous physical capacitors. Locate the HIP6004B within 3
inches of the MOSFETs, Q
MOSFETs’ gate and source connections from the HIP6004B
must be sized to handle up to 1A peak current.
Figure 6 shows the circuit traces that require additional
layout consideration. Use single point and ground plane
construction for the circuits shown. Minimize any leakage
