Note 1:
Stresses beyond those listed under Absolute Maximum Ratings –40°C to 125°C internal operating temperature range. The LTM4606MP may cause permanent damage to the device. Exposure to any Absolute is guaranteed and tested over the –55°C to 125°C internal operating Maximum Rating condition for extended periods may affect device temperature range. Note that the maximum ambient temperature reliability and lifetime. consistent with these specifications is determined by specific operating
Note 2:
The LTM4606E is guaranteed to meet performance specifications conditions in conjunction with board layout, the rated package thermal over the 0°C to 125°C internal operating temperature range. Specifications resistance and other environmental factors. over the –40°C to 125°C internal operating temperature range are assured
Note 3:
100% tested at die level only. by design, characterization and correlation with statistical process
Note 4:
See output current derating curves for different VIN, VOUT and TA. controls. The LTM4606I is guaranteed to meet specifications over the 4606fd 4 For more information www.linear.com/LTM4606 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Typical Performance Characteristics Pin Functions Block Diagram Decoupling Requirements Operation Applications Information Typical Applications Package Description Revision History Package Photograph Related Parts
