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 LT3684E is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LT3684I specications are
guaranteed over the –40°C to 125°C temperature range.
Note 3: Bias current measured in regulation. Bias current ows into the FB
pin.
Note 4: This is the minimum voltage across the boost capacitor needed to
guarantee full saturation of the switch.
The
● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VIN = 10V, VRUNS/SS = 10V VBOOST = 15V, VBIAS = 3.3V unless otherwise
noted. (Note 2)
