  • Product Details

    The MAX5072 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX5072. The MAX5072 is a dual-output DC-DC converter. One of the outputs is configured as a step-down converter (converter 1), while converter 2 is configured as a step-up converter. The EV kit is powered from a DC supply providing 5.5V to 16V. The EV kit can be reconfigured for an input voltage range between 4.5V to 5.5V.

    The MAX5072 EV kit is capable of delivering 3.3V at 2A from the step-down converter output and 12V at up to 0.22A from the step-up converter output. The MAX5072 switching frequency is set to 2.2MHz and the two outputs switch 180° out of phase. A SYNC input facilitates external frequency synchronization. Moreover, a CLKOUT output provides a clock signal that is 90° out of phase with respect to the step-up converter, allowing four-phase operation using two MAX5072 ICs in master-slave configuration.

    The MAX5072 includes a power-good output for converter 1, a reset output, and a manual reset input. Inaddition, each output, can be shut down individually. The MAX5072 features a power-fail output, which provides a logic-low when the input voltage drops below a preprogrammed threshold.

    The MAX5072 is available in a thermally enhanced 32-pin thin QFN package.
