PCB Layout Guidelines
The PCB layout and bypassing issues have been addressed with the internal design of the iP2003. One
of the most critical elements of proper PCB layout with iP2003 is the placement of the external input
bypass capacitors and the routing of the connecting power tracks. The iPOWIR Block will function
normally without any additional external input bypass capacitors. However, the addition of the external
capacitors will improve the long term reliable operation of the block.
It is recommended that the designer uses the following guidelines:
1.
2.
3.
4.
The diagram below suggests the addition of the input bypass capacitors either on the top side of
the PCB (capacitors C1-C4) or top and bottom side (C5, C6), if placement on the bottom side is
feasible. Although there is a certain degree of bypassing inside the iP2003, these external
capacitors must be placed as close to the iPOWIR device as possible.
In the diagram below, observe the routing of the power tracks that connect the external bypass
capacitors.
Provide a mid-layer solid ground plane with connections to the top through vias.
Refer to IR application note AN-1029 to determine the size of the vias and the copper weight and
thickness when designing the PCB.
