2 / 9 page ML0308 Preliminary ______________________________________________________________________________________________________ 2/9 Rev. B, July 2005 Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The ML0308 is guaranteed to meet performance specifications from 0°C to 70°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: If Lx pin exceeds the voltage limit, the ML0308 will stop switching for about 40us. ELECTRICAL CHARACTERISTICS The “X” denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 3.0V, VCE = 3.0V unless otherwise noted.
