The TPS65253 PMIC is designed to provide 3.5-A and 2.5-A continuous outputs with an operational range of 4.5
V to 16 V and an externally set switching frequency ranging from 300 kHz to 1.2 MHz. When the PMIC is not
fully loaded, buck1 can be loaded to 4 A and buck 2 to 3 A.
As there are many possible options to set the converters,
presents the performance specification
summary for the EVM.

This evaluation module is designed to provide access to the features of the TPS65253. Some modifications
can be made to this module to test performance at different input and output voltages, current and frequency
operation. Please contact TI Field Applications Group for advice on these matters.
