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:

Tlow = -40°C ; Thigh =+85°C

Note 3: This parameter is measured at latch trip point with VFB=0V.

Note 4: Comparator gain is defined as:

AV=

∆V Compensation

∆V Current Sense

Note 5: These parameters are guaranteed by design but not 100% tested

in production.
