The hold up capacitor, C1, must be placed as close as possible to the VCC pin. The compensation component C2 and R1, must be placed as close as possible to the COMP pin. The IC SOURCE pin are high frequency switching nodes. The traces must be as wide and short as possible. Keep the main traces with switching current as short and wide as possible. Place CIN, L1, R2, COUT, and D5 as close to each other as possible. Figure 2.
