EVB-EV1320QI : 3.3V, 2A DDR Termination Converter

Summary

Along with this document you will also need the latest device datasheet. The EV1320QI operates by charging a pair of capacitors in series and connecting them in parallel to generate an output voltage which is nearly one half the input voltage. There is no feedback control, and the output voltage is not regulated. The output voltage is directly proportional to the input voltage and is also affected by the load. The division by two property makes the EV1320 a suitable part for VTT applications for up to 2A of load current. The capacitor configuration around the EV1320 package determines how the device operates. For this evaluation board, the capacitors around the device have been chosen to minimize the output voltage droop as a function of load current.
