2) Place the IC and signal components. Keep the
main switching node (LX node) away from sensitive
analog components (current-sense traces and REF
capacitor). Important: The IC must be no further
than 10mm from the current-sense resistors.
Keep the gate-drive traces (DHI, DLO, and BST)
shorter than 20mm, and route them away from the
bypass capacitors close to the IC. The bulk capac-
itors can be placed further away.
3) Use a single-point star ground placed directly
below the part at the backside exposed pad of the
MAX1908/MAX8724/MAX8765/MAX8765A.
Connect the power ground and normal ground to
this node.
