Rated for 3A continuous, the MAX17574ATG+ uses internal synchronous FETs for the high-side and low-side switches. That eliminates the external catch diode.
Lower frequencies reduce switching losses for heavy-load efficiency; higher frequencies shrink the inductor and output capacitor, saving board area. The part synchronizes to an external clock if needed.
It is ROHS3 compliant.
It is a step-down (buck) switching regulator with adjustable output, synchronous rectification, and a single 3A output.
