Texas Instruments  TPS65253EVM

The TPS65253EVM is a high current, synchronous step down two buck switcher evaluation module. 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. 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.
