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 LTM4601AE/LTM4601AE-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 LTM4601AI/LTM4601AI-1 are guaranteed and tested 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. ELECTRICAL CHARACTERISTICS |
