9.10 Layout Considerations
The AS1324 requires proper layout and design techniques for optimum performance.
The power traces (GND, SW, and V IN ) should be kept as short, direct, and wide as is practical.
Pin V FB (AS1324 only) should be connected directly to the feedback resistors (R 1 and R 2 ). A potentiometer as replacement for R 1 and R 2
should be avoided to minimize the output voltage ripple and to maintain the stability of the regulator.
The resistive divider (R 1 /R 2 ) must be connected between the positive plate of C OUT and ground.
The positive plate of C IN should be connected as close to V IN as is practical since C IN provides the AC current to the internal power MOS-
FETs.
Switching node SW should be kept far away from the sensitive V FB node.
The negative plates of C IN and C OUT should be kept as close to each other as is practical. A starpoint to Ground is recommended.
