voltage threshold during normal start-up. Cycling the bias
input power off then on resets the counter and the fault latch.
Resistors (R
OCSET1
and R
OCSET2
) program the over-
current trip levels for each PWM converter. As shown in
Figure 9, the internal 200
μ
A current sink develops a voltage
across R
OCSET
(V
SET
) that is referenced to V
IN
. The DRIVE
signal enables the over-current comparator (OVER-
CURRENT1 or OVER-CURRENT2). When the voltage
across the upper MOSFET (V
DS
) exceeds V
SET
, the over-
current comparator trips to set the over-current latch. Both
V
SET
and V
DS
are referenced to V
IN
and a small capacitor
across R
OCSET
helps V
OCSET
track the variations of V
IN
due
to MOSFET switching. The over-current function will trip at a
peak inductor current (I
PEAK)
determined by:

The OC trip point varies with MOSFET’s temperature. To avoid
over-current tripping in the normal operating load range,
determine the R
OCSET
resistor from the equation above with:
1. The maximum r
DS(ON)
at the highest junction temperature.
2. The minimum I
OCSET
from the specification table.
3. Determine I

where
I is the output inductor ripple current.
For an equation for the output inductor ripple current see the
section under component guidelines titled ‘Output Inductor
Selection’.
OUT1 Voltage Program
The output voltage of the PWM1 converter is programmed to
discrete levels between 1.3V
DC
and 3.5V
DC
. This output is
designed to supply the microprocessor core voltage. The
voltage identification (VID) pins program an internal voltage
reference (DACOUT) through a TTL-compatible 5-bit digital-to-
analog converter. The level of DACOUT also sets the PGOOD
and OVP thresholds. Table 1 specifies the DACOUT voltage for
the different combinations of connections on the VID pins. The
VID pins can be left open for a logic 1 input, because they are
internally pulled up to +5V by a 10
μ
A current source. Changing
the VID inputs during operation is not recommended. The
sudden change in the resulting reference voltage could toggle
the PGOOD signal and exercise the over-voltage protection.
The ‘11111’ VID pin combination resulting in an INHIBIT
disables the IC and the open-collector at the PGOOD pin.
Application Guidelines
Soft-Start Interval
Initially, the soft-start function clamps the error amplifiers’
output of the PWM converters. After the output voltage
increases to approximately 80% of the set value, the
reference input of the error amplifier is clamped to a voltage
proportional to the SS pin voltage. The resulting output
voltage sequence is shown in Figure 6.
The soft-start function controls the output voltage rate of rise
to limit the current surge at start-up. The soft-start interval is
programmed by the soft-start capacitor, C
SS
. Programming
a faster soft-start interval increases the peak surge current.
The peak surge current occurs during the initial output
voltage rise to 80% of the set value.
Shutdown
Neither PWM output switches until the soft-start voltage
(V
SS
) exceeds the oscillator’s valley voltage. Additionally,
the reference on each linear’s amplifier is clamped to the
soft-start voltage. Holding the SS pin low (with an open drain
or collector signal) turns off all four regulators.
The ‘11111’ VID code resulting in an INHIBIT as shown in
Table 1 also shuts down the IC.
