11.3 Power Dissipation Considerations
For a given θJA, the maximum power dissipation is shown in Figure 42 and is calculated by Equation 4:
- PD = Maximum power dissipation of TLV237x IC (watts)
- TMAX = Absolute maximum junction temperature (150°C)
- TA = Free-ambient air temperature (°C)
- θJA = θJC (Thermal coefficient from junction to case) + θCA (Thermal coefficient from case to ambient air (°C/W))
Results are with no air flow and using JEDEC Standard Low-K test PCB.
