4 / 22 page LTC3537 4 3537fd 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 LTC3537 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: Specification is guaranteed by design and not 100% tested in production. ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 2) VINL = 3.3V, VOLDO = 3V, unless otherwise noted. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS PSRR Ripple Rejection f = 2.2MHz at ILOAD = 100mA (Note 3) 24 dB ISHORT Short Circuit Current Limit VOLDO = 0V l 110 150 mA VENLDOH ENLDO Input High Voltage 0.8 V VENLDOL ENLDO Input Low Voltage 0.3 V IENLDO ENLDO Input Current VENLDO = 5.5V 1.5 μA VPGDLLOW PGDL Voltage Low IPGDL = 5mA 200 mV IPGDLLEAK PGDL Leakage Current VPGDL = 5.5V 0.01 1 μA PGDL Trip Point VFBL Rising 96 % VOLDO PGDL Hysteresis 3% Note 4: Current measurements are made when the output is not switching. Note 5: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 125°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may result in device degradation or failure. Note 6: Failure to solder the exposed backside of the package to the PC board ground plane will result in a thermal resistance much higher than 68°C/W. |
