TPS82681xxEVM-589 Evaluation Module
The TPS82681xxEVM-589 facilitates the evaluation of the TPS8268xxx MicroSiP™ module family. There
are two EVMs in this family: TPS8268105EVM-589 (PWR589-001) and TPS8268180EVM-589 (PWR589-
002). PWR589-001 outputs a 1.05-V output voltage at up to 1.6 A of output current, while PWR589-002
outputs a 1.80-V output voltage at up to 1.6 A of output current. Both EVMs operate from input voltages
between 2.5 V and 5.5 V
