UNIT
Note 1: Maximum package power dissipation limits must be
observed.
Note 2: Low duty cycle pulse techniques are used during test to
maintain junction temperature as close to ambient as
possible.
Note 3: This parameter is measured at latch trip point with
VFB = 0V.
Note 4: Comparator gain is defined as:
AV=
Note 5: These parameters are guaranteed by design but not
100% tested in production.
