Product details

3A output with synchronous rectification

Rated for 3A continuous, the MAX17574ATG+ uses internal synchronous FETs for the high-side and low-side switches. That eliminates the external catch diode.

Switching frequency flexibility

The switching frequency is programmable from 100 kHz to 2.2 MHz via an external resistor. 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.

Lifecycle and sourcing posture

It is ROHS3 compliant. For a BOM line that needs a 60V-capable, 3A synchronous buck in a 4x5 mm TQFN, this part is a stable choice for new designs and ongoing production.

Frequently asked questions

What is the function of MAX17574ATG+?
