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 LTM4604A is tested under pulsed load conditions such that

TJ ≈ TA. The LTM4604AE 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 LTM4604AI is guaranteed to meet specifications over the

full 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: See output current derating curves for different VIN, VOUT and TA.
