Applications Information (continued)
⢠BST pin with respect to LX. This 0.1μF minimum
capacitor must be placed near the IC, on either
side of the PCB. Use short traces for the routing
between the capacitor and the IC.
⢠VIN pin with respect to AGND. This 0.1μF
minimum capacitor must be placed and routed
close to the IC pins. This capacitor provides
noise filtering for the input to the internal LDO.
