LMZ31704RVQT Description
The LMZ31704 power module is an easy-to-use integrated power solution that combines a 4-A DC/DC converter with power MOSFETs, a shielded inductor,
and passives into a low profile, QFN package. This total power solution allows as few as three external components and eliminates the loop compensation
and magnetics part selection process.
