Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LTC3854E 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. The LTC3854I is guaranteed to meet performance specifications over the full –40°C to 85°C operating temperature range. Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formulas: LTC3854DDB: TJ = TA + (PD • 76°C/W) LTC3854MSE: TJ = TA + (PD • 40°C/W) Note 4: The LTC3854 is tested in a feedback loop that servos VITH to a specified voltage and measures the resultant VFB. Note 5: Dynamic supply current is higher due to the gate charge being delivered at the switching frequency. See Applications Information. Note 6: Rise and fall times are measured using 10% and 90% levels. Delay times are measured using 50% levels. Not 100% tested in production. Note 7: The minimum on-time condition is specified for an inductor peak- to-peak ripple current 40% of IMAX (see Minimum On-Time Considerations in the Applications Information section). Note 8: The LTC3854 maximum LDO current specification assumes there is no external DC load current being pulled from INTVCC pin. |
