Product Details

The MAXM17712/MAXM17720/MAXM17724 evaluation kits (EV kit) provide a proven design to evaluate the performance of MAXM17712/MAXM17720/MAXM17724 modules. Each of these modules operates over a wide input range from 5.5V to 60V, and features an integrated 150mA step-down converter and 50mA linear regulator. The modules are configured to demonstrate optimum performance and component sizes in this EV kit.

MAXM17712 delivers up to 150mA from the 3.3V fixed output step-down converter, and up to 50mA from the 1.8V fixed output linear regulator. The step-down converter is configured to operate at 375kHz switching frequency, over a 5.5V to 60V input range.

MAXM17720 delivers up to 150mA from the 5V fixed output step-down converter, and up to 50mA from the 3.3V fixed output linear regulator. The step-down converter is configured to operate at 570kHz switching frequency, over an 8.4V to 60V input range.

MAXM17724 is configured to deliver up to 150mA from the adjustable output step-down converter programmed to 5V, and up to 50mA from the 2.5V fixed output linear regulator. The step-down converter is configured to operate at 570kHz switching frequency, over an 8.4V to 60V input range.

The EV kits feature provisions for selecting mode of operation (PWM or PFM), synchronization to an external clock source, enable/disable, and UVLO settings. The MAXM17710–MAXM17726 module family data sheet provides a complete description of the parts and should be read in conjunction with this data sheet prior to operating the EV kits.
