ZL2106
Once the pre-configured soft-start ramp period has expired, the
PG pin will be asserted (assuming the pre-bias voltage is not
higher than the overvoltage limit). The PWM will then adjust its
duty cycle to match the original target voltage and the output will
ramp down to the pre-configured output voltage.
FIGURE 18. OUTPUT RESPONSES TO PRE-BIAS VOLTAGES
If a pre-bias voltage higher than the overvoltage limit exists, the
device will not initiate a turn-on sequence and will declare an
overvoltage fault condition to exist. In this case, the device will
respond based on the output overvoltage fault response method
Output Overcurrent Protection
The ZL2106 can protect the power supply from damage if the
output is shorted to ground or if an overload condition is imposed
on the output. Once the current limit threshold has been selected
page 18), the user may determine the desired course of action in
response to the fault condition. The following overcurrent
protection response options are available:
1. Initiate a shutdown and attempt to restart an infinite number
of times with a preset delay period between attempts.
2. Initiate a shutdown and attempt to restart a preset number of
times with a preset delay period between attempts.

3. Continue operating for a given delay period, followed by
shutdown if the fault still exists.
4. Continue operating through the fault (this could result in
permanent damage to the power supply).
5. Initiate an immediate shutdown.
6. The default response from an overcurrent fault is an
immediate shutdown of the device. Please refer to
Application Note AN2033 for details on how to select specific
overcurrent fault response options via I 2 C/SMBus.
Thermal Overload Protection
The ZL2106 includes an on-chip thermal sensor that
continuously measures the internal temperature of the die and
will shutdown the device when the temperature exceeds the
preset limit. The factory default temperature limit is set to
+125°C, but the user may set the limit to a different value if
desired. See Application Note AN2033 for details. Note that
setting a higher thermal limit via the I 2 C/SMBus interface may
result in permanent damage to the device. Once the device has
been disabled due to an internal temperature fault, the user may
select one of several fault response options as follows:
1. Initiate a shutdown and attempt to restart an infinite number
of times with a preset delay period between attempts.
2. Initiate a shutdown and attempt to restart a preset number of
times with a preset delay period between attempts.
3. Continue operating for a given delay period, followed by
shutdown if the fault still exists.
4. Continue operating through the fault (this could result in
permanent damage to the power supply).
5. Initiate an immediate shutdown.
If the user has configured the device to restart, the device will
wait the preset delay period (if configured to do so) and will then
check the device temperature. If the temperature has dropped
below a threshold that is approximately +15°C lower than the
selected temperature fault limit, the device will attempt to
re-start. If the temperature still exceeds the fault limit the device
will wait the preset delay period and retry again.
The default response from a temperature fault is an immediate
shutdown of the device. Please refer to Application Note AN2033
for details on how to select specific temperature fault response
options via I 2 C/SMBus.
Voltage Tracking
High performance systems place stringent demands on the order
in which the power supply voltages turn on. This is particularly
true when powering FPGAs, ASICs, and other advanced processor
devices that require multiple supply voltages to power a single
die. In most cases, the I/O interface operates at a higher voltage
than the core and therefore the core supply voltage must not
exceed the I/O supply voltage according to the manufacturers'
specifications. Voltage tracking protects these sensitive ICs by
limiting the differential voltage among multiple power supplies
during the power-up and power-down sequence. The ZL2106
integrates a lossless tracking scheme that allows its output to
track a voltage that is applied to the VTRK pin with no additional
components required. Figure 19 shows a basic I2C/SMBus
tracking configuration. Please refer to Application Note AN2033
