Texas InstrumentsTPS65258EVM电源管理开发电路板和套件

The TPS65257EVM evaluation module is designed to provide access to the features of the TPS65257. The TPS65257 PMIC is designed to provide 3A, 2A, and 2 A continuous outputs with an operational range of 4.5 to 16V and a externally set switching frequency ranging from 300kHz to 2.2MHz, with automatic PFM/PWM operation. When the PMIC is not fully loaded buck1 can be loaded to 3.5A and buck 2 and 3 to 2.5A. The device also features two USB distribution switches. This evaluation module is designed to provide access to the features of the TPS65257. Some modifications can be made to this module to test performance at different input and output voltages, current and frequency operation.
