Layout Considerations
layout is very important. Using a good layout can solve
many problems associated with these types of power
supplies as transients occur.
for converter stability. They should be placed close to the
NCP3101C. The feedback trace is recommended to be kept
as far from the inductor and noisy power traces as possible.
The resistor divider and feedback acceleration circuit (R2,
R3, R6, C13) are recommended to be placed near output
feedback (Pin 16, NCP3101C).
generate voltage transients across the impedances of the
interconnecting bond wires and circuit traces. The
interconnecting impedances should be minimized by using
wide, short printed circuit traces. The critical components
should be located together as close as possible using ground
plane construction or single point grounding. The inductor
and output capacitors should be located together as close as
possible to the NCP3101C.
When designing a high frequency switching converter,
External compensation components (R1, C9) are needed
Switching current from one power device to another can
