10.4.2.2 PBTL (Outputs Paralleled after LC filter) Application Printed Circuit Board Layout Example

A. Note: PCB layout example shows composite layout. Dark grey: Top layer copper traces, light gray: Bottom layer copper traces. All PCB area not used for traces must be GND copper pour (transparent on example image)
B. Note T1: PVDD decoupling bulk capacitors should be as close as possible to the PVDD and GND_X pins, the heat sink sets the distance. Wide traces should be routed on the top layer with direct connection to the pins and without going through vias. No vias or traces must be blocking the current path.
C. Note T2: Close decoupling of PVDD with low impedance X7R ceramic capacitors is placed under the heat sink and close to the pins.
D. Note T3: Heat sink needs to have a good connection to PCB ground.
