Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTM4612E is guaranteed to meet performance specifications
over the 0°C to 125°C internal operating temperature range. Specifications
over the –40°C to 125°C internal operating temperature range are assured
by design, characterization and correlation with statistical process
controls. The LTM4612I is guaranteed to meet specifications over the

–40°C to 125°C internal operating temperature range. The LTM4612MP
is guaranteed and tested over the full –55°C to 125°C internal operating
temperature range. Note that the maximum ambient temperature is
determined by specific operating conditions in conjunction with board
layout, the rated package thermal resistance and other environmental
factors.
Note 3: 100% tested at die level only.
Note 4: See the Output Current Derating curves for different VIN, VOUT
and TA.
