1 Abstract

Industrial equipment such as a Programmable Logic Controller (PLC) need large capacitors for storing energy to provide backup time for storing critical information before equipment shutdown. In the case of DIN power supplies, the output capacitance of the load is unknown and the power supply designer has to design for a wide range of output capacitance. This application note describes how large and unknown capacitors can be powered using the TPS2663 and TPS1663 devices.
