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.
