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.

The evaluation module is designed to provide access to the features of the TPS65265. Some modifications
can be made to this module to test performance at different input and output voltages, current and switching
frequency. Please contact the TI Field Applications Group for advice on these matters.
