LTM4600HV
Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C, VIN = 12V. External CIN = 120µF, COUT = 200µF/Ceramic per typical
application (front page) configuration.

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 LTM4600HVE 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 LTM4600HVI
is guaranteed over the –40°C to 85°C temperature range. The
LTM46000HVMP is guaranteed and tested over the –55°C to 125°C
temperature range.
Note 3: For output current derating at high temperature, please refer to
Thermal Considerations and Output Current Derating discussion.
Note 4: Test assumes current derating versus temperature.
Note 5: Guaranteed by correlation.
