MAX1534 Evaluation Kit
General Description
The MAX1534 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that demon-
strates the MAX1534 triple-output keep-alive power sup-
ply 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.
