ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are TA = 25°C. VCC = CHARGE = 5V, CLAMP = 0V, unless otherwise noted. Individual 25kΩ
resistors tied from 5V VTRANS supply to RVTRANS, RVOUT, RDCM, unless otherwise noted. (Note 2)

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 LT3751E 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
LT3751I is guaranteed over the full –40°C to 125°C operating junction
temperature range.
Note 3: A 60V internal clamp is connected to RVTRANS, RDCM, RVOUT,
UVLO1, UVLO2, OVLO1 and OVLO2. Resistors should be used such that
the pin currents do not exceed the Absolute Maximum Ratings.
Note 4: Currents will increase as pin voltages are taken higher than the
internal clamp voltage.
Note 5: Refer to Block Diagram for VTRANS and VDRAIN denitions.
Note 6: Low noise regulation of the output voltage requires a resistive
voltage divider from output voltage to FB pin. FB pin should not be
grounded in this conguration. Refer to the Typical Application diagram for
proper FB pin conguration.
Note 7: The feedback pin has built-in hysteresis that denes the boundary
between charge-only mode and low noise regulation mode.
Note 8: LVGATE should be used in parallel with HVGATE when VCC is less
than or equal to 8V (LVGATE active). When not in use, LVGATE should be
tied to VCC (LVGATE inactive).
Note 9: Do not apply a positive or negative voltage or current source to
HVGATE, otherwise permanent damage may occur.
