Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Remote sense amplifier recommended for ≤3.3V output. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
100% tested at wafer sort only. Maximum Rating condition for extended periods may affect device
Note 5:
See output current derating curves for different V reliability and lifetime. IN, VOUT and TA.
Note 2:
The LTM4603/LTM4603-1 is tested under pulsed load conditions such that TJ ≈ TA. The LTM4603E/LTM4603E-1 are guaranteed to meet performance specifications from 0°C to 85°C. Specifications over the –40°C to 85°C operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4603I/LTM4603I-1 are guaranteed over the –40°C to 85°C operating temperature range. 4603fb 4 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Simplified Block Diagram Decoupling Requirements Operation Applications Information Typical Application Package Description Revision History Typical Application Package Photograph Related Parts
