15 / 18 page ![]() SC560 15 Layout Considerations While layout for linear devices is generally not as critical as for a switching application, careful attention to detail will ensure reliable operation. The diagram below illustrates proper layout of a circuit using the SC560A. For variants that don’t require current setting resistors, these devices can be omitted from the layout. Attach the part to a large copper footprint, to enable better heat transfer from the device on PCBs where there are internal power and ground planes. • Applications Information (continued) Place the input, output, and bypass capacitors close to the device for optimal transient response and device behavior. Connect all ground connections directly to the ground plane whenever possible to minimize ground potential di erences on the PCB. Ensure that the feedback resistors are placed as close as possible to the feedback pins. • • • R 1 R 2 R 3 R 4 C 4 C 3 C 2 C 1 1 U1 U1 = SC560A |
