  • Product Details

    The MAX5090 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a step-down DC-DC switching regulator. The circuit utilizes a MAX5090C adjustable converter configured for a +5V output at up to 2A of current. The converter operates from a wide +7.5V to +76V input range.

    The MAX5090 IC features a built-in high-side switch and automatic pulse-skipping mode operation. The MAX5090 EV kit demonstrates low quiescent current and high efficiency up to 90%. The MAX5090 IC switches at 127kHz but can be synchronized with an external clock to operate at a switching frequency between 119kHz and 200kHz.

    The MAX5090 EV kit is a fully assembled and tested surface-mount circuit board. It can also be used to test other fixed output-voltage versions: MAX5090A (3.3V) and MAX5090B (5.0V).

    Warning: The MAX5090 EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment connected to it. Users who power up this EV kit or power the sources connected to it must be careful to follow appropriate safety procedures when working with high-voltage equipment.

    Under severe fault or failure conditrions, this EV kit may dissipate large amounts of power, which could result in the mechanical ejection of a component or component debris and high velocity. Operate this EV kit with care to avoid possible injury.
