Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: To calculate maximum switch “on” voltage at currents between
low and high conditions, a linear interpolation may be used.
Note 3: A feedback pin voltage (VFB) of 2.5V forces the VC pin to its low
clamp level and the switch duty cycle to zero. This approximates the zero
load condition where duty cycle approaches zero.
Note 4: Total voltage from VIN pin to ground pin must be ≥ 8V after start-
up for proper regulation.
Note 5: Switch frequency is internally scaled down when the feedback pin
voltage is less than 1.3V to avoid extremely short switch on times. During
testing, VFB is adjusted to give a minimum switch on time of 1s.
Note 6: ILIM ≈
(LT1074)
, ILIM ≈
(LT1076).
Note 7: Switch to input voltage limitation must also be observed.
Note 8: VMAX = 40V for the LT1074/76 and 60V for the LT1074HV/76HV.
Note 9: Does not include switch leakage.
