Product Details

The MAX1534 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that demonstrates the MAX1534 triple-output keep-alive power supply IC. The MAX1534 integrates one high-performance step-down converter and two low-dropout regulators (LDOs). The step-down converter is configured for 5.0V and provides up to 500mA. The first and second LDOs are configured for 3.3V and 1.8V at currents up to 160mA each. Power management functions include an accurate shutdown input and power-OK (POK) output. The EV kit also allows for adjustable output voltages by including extra pads for feedback resistors.
