destructive ringing of the capacitors and output inductors. If the
conditions that caused the over-voltage still persist, the PWM
outputs will be cycled between three state and VCORE
clamped to ground, as a hysteretic shunt regulator.
Under-Voltage
The VSEN pin also detects when the CORE voltage falls more
than 10% below the VID programmed level. This causes PGOOD
to go low, but has no other effect on operation and is not latched.
There is also hysteresis in this detection point.
Over-Current
In the event of an over-current condition, the over-current
protection circuit reduces the average current delivered to less
than 25% of the current limit. When an over-current condition is
detected, the controller forces all PWM outputs into a three
state mode. This condition results in the gate driver removing
drive to the output stages.The HIP6311A goes into a wait delay
timing cycle that is equal to the Soft-Start ramp time. PGOOD
also goes “low” during this time due to VSEN going below its
threshold voltage.To lower the average output dissipation, the
Soft-Start initial wait time is increased from 32 to 2048 cycles,
then the Soft-Start ramp is initiated. At a PWM frequency of
200kHz, for instance, an over-current detection would cause a
dead time of 10.24ms, then a ramp of 10.08ms.
At the end of the delay, PWM outputs are restarted and the
Soft-Start ramp is initiated. If a short is present at that time, the
cycle is repeated. This is the hiccup mode.
Figure 6 shows the supply shorted under operation and the
hiccup operating mode described above. Note that due to the
high short circuit current, over-current is detected before
completion of the start-up sequence so the delay is not quite
as long as the normal Soft-Start cycle.
CORE Voltage Programming
The voltage identification pins (VID0, VID1, VID3, and VID4)
set the CORE output voltage. Each VID pin is pulled to VCC by
an internal 20
A current source and accepts open-
collector/open-drain/open-switch-to-ground or standard low-
voltage TTL or CMOS signals.
Table 1 shows the nominal DAC voltage as a function of the
VID codes. The power supply system is
0.5% accurate over
the operating temperature and voltage range.
