4 / 28 page  LTC3835-1 4 38351fc ELECTRICAL CHARACTERISTICS Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formulas: LTC3835GN-1: TJ = TA + (PD • 90°C/W) LTC3835EDHC-1: TJ = TA + (PD • 43.5°C/W) Note 4: The LTC3835-1 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. 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).
