The SE9135 has built-in thermal protection. When the thermal limit is ex ceeded, the IC will enter protection, and VOUT will be pulled to ground. The power dissipation for a given application can be calculated as following: The power dissipation (P D) is PD = IOUT * [VIN – VOUT] The thermal limit of the package is then limited to P D(MAX) = [TJ – TA]/ΘJA where TJ is the junction temperature, TA is the ambient temperature, and ΘJA is around 180°C/W for SE9135. SE913 5 is designed to enter thermal protection at 150°C. For example, if T A is 25°C then the maximum P D is limited to about 0.7W. In other words, if IOUT(MAX) = 350mA, then [VIN – VOUT] cannot exceed 2V.
