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 LTM4613 is tested under pulsed load conditions such that
TJ ≈ TA. The LTM4613E 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 LTM4613I is guaranteed to meet specifications over the
–40°C to 125°C internal operating temperature range. The LTM4613MP
is guaranteed and tested over the full –55°C to 125°C internal operating
temperature range. Note that the maximum ambient temperature
consistent with these specifications 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.
Note 5: Guaranteed by design.
