The following are guidelines for mounting the exposed pad IC on a Multi-Layer PCB with ground a plane.

The efficiency of this method depends on several factors, including die area, number of thermal vias, thickness of copper, etc. Specifications subject to change WWW.TRIUNESYSTEMS.COM - 10 - Copyright © 2012, Triune Systems, LLC TS14001 Version 1.5 Mold compound Die Epoxy Die attach Exposed pad Solder 5% - 10% Cu coverage Single Layer, 2oz Cu Ground Layer, 1oz Cu Signal Layer, 1oz Cu Thermal Vias with Cu plating 90% Cu coverage 20% Cu coverage Bottom Layer, 2oz Cu Note: NOT to Scale The above drawing is a representation of how the heat can be conducted away from the die using an exposed pad package. Each application will have different requirements and limitations and therefore the user should use sufficient copper to dissipate the power in the system. The output current rating for the linear regulators may have to be de-rated for ambient temperatures above 85C. The de-rate value will depend on calculated worst case power dissipation and the thermal management implementation in the application. APPLICATION USING A SINGLE LAYER PCB Use as much Copper Area as possible for heat spread Package Thermal Pad Package Outline Layout recommendations for a Single Layer PCB: utilize as much Copper Area for Power Management. In a single layer board application the thermal pad is attached to a heat spreader (copper areas) by using low thermal impedance attachment method (solder paste or thermal conductive epoxy). In both of the methods mentioned above it is advisable to use as much copper traces as possible to dissipate the heat. IMPORTANT: If the attachment method is NOT implemented correctly, the functionality of the product is not guaranteed. Power dissipation capability will be adversely affected if the device is incorrectly mounted onto the circuit board.
