Note 1: Maximum package power dissipation limits must be observed.
Note 4: Comparator gain is defined as:
∆V Compensation
∆V Current Sense
Note 2: Low duty cycle pulse techniques are used during test to maintain
junction temperature as close to ambient as possible:
AV=
Tlow = -40°C ; Thigh =+85°C
Note 3: This parameter is measured at latch trip point with VFB=0V.
Note 5: These parameters are guaranteed by design but not 100% tested
in production.
