8.4.3 Power Dissipation

The maximum IC junction temperature must be restricted to 150°C under normal operating conditions. To calculate the maximum allowable power dissipation, PD(max) for a given output current and ambient temperature, use Equation 3.

Equation 3. TPS22996H-Q1

where

  • PD(max) is the maximum allowable power dissipation.
  • TJ(max) is the maximum allowable junction temperature (150°C for the TPS22996H).
  • TA is the ambient temperature of the device.
  • θJA is the junction to air thermal impedance. See Section 5.4. This parameter is highly dependent upon board layout.
