  • Product Details

    The MAX8556 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board demonstrating the MAX8556 low-dropout (LDO) regulator. The EV kit comes assembled with a MAX8556ETE circuit that steps down a 1.425V to 3.6V input voltage range to a 1.2V output capable of sourcing up to 4A (limited by power dissipation). The MAX8556 features a POK output that goes high impedance once the output is within ±10% of its regulation value. The device utilizes an internal p-channel MOSFET for reduced dropout and quiescent current. In addition, the p-channel MOSFET eliminates the need for an external bias or noisy charge pump. The MAX8556 EV kit can also be used to evaluate the MAX8557 with no component changes.
