LM2622
SNVS068E –MAY 2000–REVISED MARCH 2013 www.ti.com
POWER DISSIPATION
The output power of the LM2622 is limited by its maximum power dissipation. The maximum power dissipation is
determined by the formula
P
D
= (T
jmax
- T
A
)/θ
JA
where
• T
jmax
is the maximum specidfied junction temperature (125°C)
• T
A
is the ambient temperature
• θ
JA
is the thermal resistance of the package (21)
θ
JA
is dependant on the layout of the board as shown below.
