ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the specified internal operating temperature range. Specified as each individual output channel. TA = 25°C (Note 2), SVIN = VIN = 12V, unless otherwise noted. Per the typical application in Figure 30. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
The minimum on-time is tested at wafer sort. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
See output current derating curves for different VIN, VOUT and TA. Maximum Rating condition for extended periods may affect device
Note 5:
Guaranteed by design. reliability and lifetime.
Note 6:
100% tested at wafer level.
Note 2:
The LTM4671 is tested under pulsed load conditions such that TJ ≈ TA. The LTM4671E is guaranteed to meet performance specifications over the 0°C to 125°C internal operating temperature range. Specifications over the full –40°C to 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4671I is guaranteed to meet specifications over the full –40°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.
