ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VIN = 20V, Boost – SW = 4V, SHDN = 2V, VFB = 3.3V, CTIMER = 0.68μF.
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 LT3652EDD is guaranteed to meet performance specications
from 0°C to 125°C junction temperature. Specications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization, and correlation with statistical process controls. The
LT3652IDD specications are guaranteed over the full –40°C to 125°C
operating junction temperature range. High junction temperatures degrade
operating lifetimes.
Note 3: VIN minimum voltages below the start threshold are only
supported if (VBOOST-VSW) > 2V.
Note 4: This parameter is valid for programmed output battery oat
voltages ≤ 4.2V. VIN operating range minimum is 0.75V above the
programmed output battery oat voltage (VBAT(FLT) + 0.75V). VIN Start
Voltage is 3.3V above the programmed output battery oat voltage
(VBAT(FLT) + 3.3V).
Note 5: Output battery oat voltage (VBAT(FLT)) programming resistor
divider equivalent resistance = 250k compensates for input bias current.
Note 6: All VFB voltages measured through 250k series resistance.
Note 7: VSENSE(DC) is reduced by thermal foldback as junction temperature
approaches 125°C.
