The external capacitors must be carefully selected to SE8119 Thermal Considerations It is important that the thermal limit of the package is not exceeded. thermal protection. The SE8119 has built-in When the thermal limit is exceeded, 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 (PD) is PD = IOUT - [VIN – VOUT] It The thermal limit of the package is then limited to PD(MAX) = [TJ – TA]/ΘJA where TJ is [...]
