Applications Information
Operation with 12V Adapter
Layout Procedure
Careful PCB layout is critical to achieve high efficiency
and low EMI. Follow these layout guidelines for optimum
performance:
1) Place the input capacitor, classification resistor, and
transient voltage suppressor as close as possible to
the MAX5981A/MAX5981B.
2) Use large SMT component pads for power dissipat-
ing devices such as the MAX5981A/MAX5981B and
the external diodes.
3) Use short and wide traces for high-power paths.
4) Use the MAX5981A/MAX5981B evaluation kit layout
as a reference.
5) Place enough vias in the pad for the EP of the
MAX5981A/MAX5981B so that heat generated inside
can be effectively dissipated by the PCB copper.
The recommended spacing for the vias is 1mm to
1.2mm pitch. The thermal vias should be plated (1oz
copper) and have a small barrel diameter (0.3mm to
0.33mm).
