(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
(2) These test conditions also included a PCB sized at 101.3mm x 152.4mm incorporating the recommended PCB thermal enhancements specified in Section 9.1.1. In addition, airflow is parallel to the board surface directed at the device.
(3) See Table 6-1 for thermal parameters based on the example heat-sinks listed below
  1. Heatsink-7 W: S1525-7W, Size = 25 mm x 25 mm x 7 mm, Pins = 7 x7 = 49 (Vendor: Alpha, Type S Series)
  2. Heatsink-15 W: S1530-15W, Size = 30 mm x 3 0mm x 15 mm, Pins = 8 x 8 = 64 (Vendor: Alpha, Type S Series)
(4) Due to the complex internal construction of the DLPC6540 controller, the RJC and RJB thermal coefficients do not always produce an accurate junction temperature estimate. A limited set of comparison scenario data shows that the RJC and RJB modeled junction temperature can have a +9% to -2% error vs the actual temperature. The amount of this error varies with the use and size of an external heat sink as well as the amount of external air flow. Validate all thermal estimates based on RJC and RJB with an actual temperature measurement at the top-center of the package plus the delta-temp defined by ψJT.
(5) Example: Using the power we expect of 11.31 W
11.31 W * 0.6 °C/W = 6.786 °C = > TC-max = 115 °C - ~7 °C = 108 °C
(6) PMAX = (TJ-max - TA-max) / RθJA
