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 LTM4618 is tested under pulsed load conditions such that

over the 0°C to 125°C operating junction temperature 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 LTM4618I is guaranteed to meet specifications over the full

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: 100% tested at wafer level only.
