Soft-start delay time
t
SSDEL
is the time
to charge
SS/DEL up to 1.3V. After this the error amplifier output is released to
allow the soft start. The soft start time
t
SS
represents the time during which converter voltage rises from zero to V
O.
t
SS
can be programmed by C

Over Current Protection (OCP)
The current limit threshold is set by a resistor connected between the OCSET and VDAC pins. If the average Current
Sense Amplifier output plus VDAC voltage exceeds the OCSET voltage, the over-current protection is triggered.
A delay is included if an over-current condition occurs after a successful soft-start sequence. This is required since over-
current conditions can occur as part of normal operation due to load transients or VID transitions. If an over-current fault
occurs during normal operation, the Over Current Comparator will initiate the discharge of the capacitor at SS/DEL but
will not set the fault latch immediately. If the over-current condition persists long enough for the SS/DEL capacitor to
discharge below the 250mV offset of the delay comparator, the Fault latch will be set pulling the Error Amplifier
’s output
low inhibiting switching in the phase ICs and de-asserting the PWRGD signal. See Soft Start, Over-Current Fault Delay,
and Hiccup Mode.
The inductor DC resistance R
L
is utilized to sense the inductor current. I
LIMIT
is
the required over current limit. I
OCSET,
the
bias current of OCSET pin, is set by R
ROSC
and is also determined by the curve in the Typical Operating Characteristics.
R
OCSET
is defined in the following Equation (8).
