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 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 LT3684I speciﬁcations are

guaranteed over the –40°C to 125°C temperature range.

Note 3: Bias current measured in regulation. Bias current ﬂows 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 speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VIN = 10V, VRUNS/SS = 10V VBOOST = 15V, VBIAS = 3.3V unless otherwise

noted. (Note 2)
