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: To calculate maximum switch “on” voltage at currents between
low and high conditions, a linear interpolation may be used.
Note 3: A sense pin voltage (V SENSE ) of 5.5V 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.
current limit testing, V SENSE is adjusted to give a minimum switch on time
of 1ms.
Note 6: Switch to input voltage limitation must also be observed.
Note 7: V MAX = 40V for the LT1076-5 and 60V for the LT1076HV-5.
Note 8: Error ampli?er voltage gain and transconductance are
speci?ed relative to the internal feedback node. To calculate gain and
transconductance from the Sense pin (Output) to the V C pin, multiply by
0.44.
Note 9: Does not include switch leakage.
Note 4: Total voltage from V IN pin to ground pin must be ≥ 8V after start-
up for proper regulation. For T A < 25°C, limit = 5V.
Note 5: Switch frequency is internally scaled down when the sense pin
