Efficiency vs Load Current
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the –40°C to 125°C
internal operating temperature range. TA = 25°C, VIN = 5V unless otherwise noted. Per the typical application in Figure 18. Specified
as each channel (Note 3).

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 LTM4616E 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 LTM4616I is guaranteed to meet specifications over the full
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: Two channels are tested separately and the same testing
conditions are applied to each channel.
Note 4: See Output Current Derating curves for different VIN, VOUT and TA.
