    The TPS65252EVM is a high current, synchronous step down three buck switcher evaluation module. The user’s guide document presents the information required to power the TPS65252 PMIC as well as the support documentation including schematic and bill of materials. The TPS65252 PMIC is designed to provide 3-A and 2-A continuous outputs with an operational range of 4.5 V to 18 V and a externally set switching frequency ranging from 300 kHz to 2.2 MHz. When the PMIC is not fully loaded, buck1 can be loaded to 3.5 A and buck 2 to 2.5 A. It also features a power distribution switch with selectable current limit.
