SLVA833D October 2016 – May 2021 TPS2660 , TPS2662 , TPS2663
Figure 10-1 shows the performance of the TPS2660 for 10 ms supply interruption. During power-fail, the output bulk capacitor supplies the system load. When supply voltage resumes, the TPS2660 charges the output capacitance with the current limit.
Figure 10-2 shows the startup of the TPS2660 when the supply voltage is ramped up. The circuit limits charging current to the bulk capacitor and simultaneously provides the required load current.
