3 Schematic Figure 3-1 illustrates the TPS65253 EVM schematic. The resistor and capacitor values have been chosen according to the guidelines presented on the TPS65253 spec available at http://focus.ti.com/docs/ prod/folders/print/TPS65253.html. Note that for the purpose of gains-phase measurements R9 and R11 (0 Ω on the EVM) need to be replaced by suitable low value resistors as per the network analyzer setup required. -
