TYPICAL APPLICATION
LOW COST OVERVOLTAGE PROTECTION
There is an alternative method to implementing the over-
voltage protection using a resistor divider at the FILTER
pin (see Figures 27 and 28). In this implementation, the
SLOW COMP is NULL in Normal Mode. Only the FAST
COMP circuit breaker is available and the current limit
level is 150mV/R
SENSE
. During the soft-cycle, the inrush
current servo loop is at 50mV/R
SENSE
. So, the heavy load
should only turn on at/after the end of second cycle where
the RESET pin goes high.

(In Normal Mode, SLOW COMP Is Disabled. In Soft-Start Cycle, I
SOFTSTART
 Is Still 50mV/R
SENSE
