LTM4611
Electrical Characteristics
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 LTM4611 is tested under pulsed load conditions such that
TJ ≈ TA. The LTM4611E is guaranteed to meet performance specifications
over the 0°C to 125°C operating junction temperature (TJ) range.
Specifications over the full –40°C to 125°C operating junction temperature
range are assured by design, characterization and correlation with
statistical process controls. The LTM4611I is guaranteed to meet
specifications over the full –40°C to 125°C operating junction 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: Consistent with Pb-free 260°C peak IR reflow soldering profiles.
See Application Note 100.
Note 4: See output current derating curves for different VIN, VOUT and TA.
Note 5: The minimum on-time condition is specified for a peak-to-peak
inductor ripple current of ~40% of IMAX Load. (See the Typical Applications
section)
