FUNCTIONAL DESCRIPTION
PULSEWIDTH COMPARATOR
A ground compatible comparator generates the
PWM signal whichcontrols thegate of theexternal
powerMOS.
The slopes of the leading and trailing edgesof the
gate driving signal are defined by the external ca-
pacitorC
S
accordingto :

Thisfeature allows to optimize theswitching speed
for the power and RFI performancebest suited for
the application.
The lower limit of the duty cycle is fixed at 15 % of
the ratio between the input and the reference vol-
tage(seefig. 1).Inputvoltageslowerthanthisvalue
disable the internal oscillator signal and therefore
the gate driver.
GROUNDCOMPATIBLE TRIANGLE
OSCILLATOR
The triangle oscillator provides the switching fre-
quencyf

If the pin PWL (power limitation) is connected to
ground and Vs is higher than the PWL threshold
voltage,theduty cycle and thef

frequencyare re-
duced:this allowstotransferacostantpowertothe
load (see fig. 2).
TIMER AND PROTECTION LATCH
When an overcurrent occurs, the device starts
charging the external capacitor C
