5 Conclusion

Powering large capacitive loads through constant inrush current can lead to hiccups in start-up due to thermal shutdown whereas powering large capacitive load with constant power dissipation in power switch need an external MOSFET to withstand the power dissipation during start-up. The TPS2663 and TPS1663 devices with integrated thermal regulation and MOSFET provide an optimized solution for achieving fast and reliable start-up with large and unknown capacitive loads.
