In board pattern design, the wiring of power supply line should be low Impedance, and put the bypass capacitor if necessary.
Especially the wiring impedance must be lower around the DC/DC converter.
In heat design, operate the DC/DC converter in the following condition.
(The following temperature is a guarantee temperature, so consider the margin.)
1. Periphery temperature Ta must be less than 85
2. The loss of IC must be less than dissipation Pd.
