Texas InstrumentsTPS65270EVMEnergiemanagement, Entwicklungsplatinen und -kits

The TPS65270EVM evaluation module is designed to provide access to the features of the TPS65270. The TPS65270 PMIC is designed to provide 2-A and 3-A continuous currents with an operational range of 4.5 V to 16 V and an externally set switching frequency ranging from 300 kHz to 1.4 MHz. When the PMIC is not fully loaded, Buck1 can be loaded to 2.5 A and Buck2 to 3.5 A
