11.3 Thermal Considerations

The underlying thermal limitation for the DLPC150 is that the maximum operating junction temperature (TJ) not be exceeded (this is defined in the Recommended Operating Conditions). This temperature is dependent on operating ambient temperature, airflow, PCB design (including the component layout density and the amount of copper used), power dissipation of the DLPC150, and power dissipation of surrounding components. The DLPC150’s package is designed primarily to extract heat through the power and ground planes of the PCB. Thus, copper content and airflow over the PCB are important factors.

The recommended maximum operating ambient temperature (TA) is provided primarily as a design target and is based on maximum DLPC150 power dissipation and RθJA at 0 m/s of forced airflow, where RθJA is the thermal resistance of the package as measured using a glater test PCB with two, 1-oz power planes. This JEDEC test PCB is not necessarily representative of the DLPC150 PCB; the reported thermal resistance may not be accurate in the actual product application. Although the actual thermal resistance may be different, it is the best information available during the design phase to estimate thermal performance. However, after the PCB is designed and the product is built, TI highly recommends that thermal performance be measured and validated.

To do this, measure the top center case temperature under the worse case product scenario (max power dissipation, max voltage, max ambient temperature) and validated not to exceed the maximum recommended case temperature (TC). This specification is based on the measured φJT for the DLPC150 package and provides a relatively accurate correlation to junction temperature. Take care when measuring this case temperature to prevent accidental cooling of the package surface. TI recommends a small (approximately 40 gauge) thermocouple. The bead and thermocouple wire should contact the top of the package and be covered with a minimal amount of thermally conductive epoxy. The wires should be routed closely along the package and the board surface to avoid cooling the bead through the wires.
