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 LTM4601HV is tested under pulsed load conditions such
that T_J ≈ T_A. The LTM4601HVE is 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 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 V_IN, V_OUT and T_A.
