Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
The LTM4601HV is tested under pulsed load conditions such may cause permanent damage to the device. Exposure to any Absolute that TJ ≈ TA. The LTM4601HVE 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 LTM4601HVI is guaranteed over the –40°C to 85°C temperature range.
Note 3:
Remote sense amplifier recommended for ≤3.3V output.
Note 4:
100% tested at wafer level only.
Note 5:
See output current derating curves for different VIN, VOUT and TA. 4601hvfb 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 Applications Package Description Revision History Package Photos Related Parts
