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:
2) Use large SMT component pads for power dissipat-
ing devices such as the MAX5969A/MAX5969B and
the external diodes.
3) Use short and wide traces for high-power paths.
4) Use the MAX5969 Evaluation Kit layout as a refer-
ence.
1) Place the input capacitor, classification resistor, and
transient voltage suppressor as close as possible to
the MAX5969A/MAX5969B.
