Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Two channels are tested separately and the same testing may cause permanent damage to the device. Exposure to any Absolute conditions are applied to each channel. Maximum Rating condition for extended periods may affect device
Note 4:
See Output Current Derating curves for different VIN, VOUT and TA. reliability and lifetime.
Note 2:
The LTM4616 is tested under pulsed load conditions, such that TJ ≈ TA. The LTM4616E 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 LTM4616I is guaranteed to meet specifications over the –40°C to 125°C internal operating temperature range. The LTM4616MP is guaranteed and tested over the –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. 4616ff 4 For more information www.linear.com/LTM4616 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Pin Functions Simplified Block Diagram Operation Applications Information Package Description Revision History Package Photo Related Parts Design Resources
