3 / 16 page LTC3542-1 3 35421f 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. No pin should exceed 6V. Note 2: The LTC3542-1 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. Note 3: Failure to solder the Exposed Pad of the package to the PC board will result in a thermal resistance much higher than 89°C/W. Note 4: The converter is tested in a proprietary test mode that connects SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS VUVLO Undervoltage Lockout Threshold VIN Rising VIN Falling 1.8 2.0 1.9 2.3 V V VRUN RUN Threshold l 0.3 1.5 V IRUN RUN Leakage Current l ±0.01 ±1 μA VMODE/SYNC MODE/SYNC Threshold l 0.3 1.2 V IMODE/SYNC MODE/SYNC Leakage Current l ±0.01 ±1 μA the output of the error amplifier to the SW pin, which is connected to an external servo loop. Note 5: Dynamic supply current is higher due to the internal gate charge being delivered at the switching frequency. Note 6: The DFN switch on resistance is guaranteed by correlation to wafer level measurements. Note 7: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: TJ = TA + (PD) • (θJA). ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 3.6V unless otherwise noted. |
