ELECTRICAL CHARACTERISTICS

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 LTC3207E/LTC3207E-1 are guaranteed to meet performance

speciﬁcations from 0°C to 85°C. Speciﬁcations over the –40°C to

85°C ambient operating temperature range are assured by design,

characterization and correlation with statistical process controls.

Note 3: Based on long term current density limitations. Assumes operating

duty cycle of <10% under absolute maximum conditions for durations less

than 10 seconds.

Note 4: This IC includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed 125°C when overtemperature protection is active.

Continuous operation above the speciﬁed maximum operating junction

temperature may result in device degradation or failure.

Note 5: 1.5x mode output impedance is deﬁned as (1.5VBAT – VCPO)/IOUT.

2x mode output impedance is deﬁned as (2VBAT – VCPO)/IOUT.

Note 6: All values are referenced to VIH and VIL levels.

Note 7: Guaranteed by design.

The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VBAT = 3.6V, DVCC = 3V, ENU = Hi, CAMHL = LO, C1 = C2 = C3 = 2.2µF,

C4 = 4.7µF, unless otherwise noted.
