denotes the specifications which apply over the specified operating temperature range, otherwise specifications are at TA = 25°C. (Notes 2, 3) VIN = 3.3V, VEN = VIN, MODE/SYNC = 0V, unless otherwise noted. PARAMETER CONDITIONS MIN TYP MAX UNITS
SYNC Level High on MODE/SYNC l 1.2 V SYNC Level Low on MODE/SYNC l 0.4 V Minimum MODE/SYNC Pulse Width 40 ns MODE/SYNC Input Resistance 200 kΩ MODE/SYNC No Clock Detect Time 20 µs MODE/SYNC Clock Out Rise/Fall Time CMODE/SYNC = 50pF 10 ns MODE/SYNC Clock Low Output Voltage IMODE/SYNC = 100µA 0.2 V MODE/SYNC Clock High Output Voltage IMODE/SYNC = 100µA VIN – 0.2 V MODE/SYNC Clock Out Duty Cycle 50 %
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
The LTC3310S includes overtemperature protection which may cause permanent damage to the device. Exposure to any Absolute protects the device during momentary overload conditions. Junction Maximum Rating condition for extended periods may affect device temperatures will exceed 150°C when overtemperature protection is reliability and lifetime. active. Continuous operation above the specified maximum operating
Note 2:
The LTC3310SE is guaranteed to meet performance specifications junction temperature may impair device reliability. from 0°C to 125°C junction temperature. Specifications over the –40°C
Note 4:
Supply current specification does not include switching currents. to 125°C operating junction temperature range are assured by design, Actual supply currents will be higher. characterization, and correlation with statistical process controls. The LTC3310SI Is guaranteed over the –40°C to 125°C operating junction temperature range. Rev.
