TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information 9.1.1 Thermal Consideration It is recommended to limit the junction temperature (TJ) to below 125°C. To calculate the maximum allowable dissipation, PD(max) for a given output current and ambient temperature, use Equation 1 as a guideline: where • PD(max) is maximum allowable power dissipation • TJ(max) is maximum allowable junction temperature • TA is ambient temperature of the device • ΘJA is junction to air thermal impedance. See the Thermal Information section. This parameter is highly dependent upon board layout (1) 9.1.2 Power Sequencing The TPS22971 has an integrated power good indicator which can be used for power sequencing. As shown in Figure 3, the switch to the second load is controlled by the PG signal from the first switch. This ensures that the power to load 2 is only enabled after the power to load 1 is enabled after the first switch has turned on. |
