Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
The LTM4603HV is tested under pulsed load conditions such may cause permanent damage to the device. Exposure to any Absolute that TJ ≈ TA. The LTM4603HVEV is guaranteed to meet performance Maximum Rating condition for extended periods may affect device specifications from 0°C to 85°C. Specifications over the –40°C to 85°C reliability and lifetime. operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4603HVIV is guaranteed over the –40°C to 85°C operating temperature range.
Note 3:
Remote sense amplifier recommended for ≤3.3V output.
Note 4:
100% tested at die level only.
Note 5:
See output current derating curves for different VIN, VOUT and TA. 4603hvfa 4 For more information www.linear.com/LTM4603HV Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Decoupling Requirements Operation Applications Information Typical Applications Package Description Revision History Related Parts
