Note1: Absolute Maximum Ratings are those values
beyond which the life of a device may be impaired.
Note 2: The ML3406 is guaranteed to meet performance
specifications from 0°C to 70°C. Specifications over the
-40°C to 85°C operating temperature range are assured
by design, characterization and correlation with statistical
process controls.
∗:apply over the full operating temperature range.
Note 3: Tj=Ta + (PD) (250°C/W)
Note 4: The ML3406 is tested in a proprietary test mode
that connects VFB to the output of the error amplifier.
Note 5: Dynamic supply current is higher due to the gate
charge being delivered at the switching frequency.
