LM3630A Switch Current Limit

Other Parts Discussed in Thread: LM3630A

Hello,

The datasheet for the LM3630A shows 4 different switch current limit ranges, but does not specify the condition. 

I_CL
NMOS switch current limit 
2.5V < Vin < 5.5V
min | typ | max  (mA)
480  600  720
640  800  960
800 1000 1200
960 1200 1440

In section 7.3.3.2 "Current Limit" it states "The switch current limit for the LM3630A device’s inductive boost is set at 1 A."


Thanks very much for your help.  Keith
