Datasheet
● Attention point of board layout
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.
● About heat loss
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.
● Application example
? LED current setting controlled ISETH resistor.
