Note 1: Maximum package power dissipation limits must be observed.
Note 3: Adjust VCC above the Start-Up threshold before setting to 15V.
Note 4: This parameter is measured at latch trip point with VFB=0V.
Note 5: Comparator gain is defined as:
AV =
Note 6: These parameters are guaranteed by design but not 100% tested
in production.
Note 7: Low duty cycle pulse techniques are used during test to main-
tain junction temperature as close to ambient as possible: Tlow=0°C ;
Thigh=+70°C
