1 Background

The TPS65265 PMIC is a triple 5-A/3-A/2-A output current, synchronous step-down (buck) converter with an operational range of 4.5 to 17 V. The feedback voltage reference for each buck is 0.6 V. Each buck is independent with dedicated enable and loop compensation. The TPS65265 supports PSM mode and FCC mode.

As there are many possible options to set the converters, Table 1-1 presents the performance specification summary for the EVM.
