Feature Descriptions
Voltage Sequencing
Austin SuperLynx
a sequencing feature, EZ-SEQUENCE
users to implement various types of output voltage
sequencing in their applications. This is
accomplished via an additional sequencing pin.
When not using the sequencing feature, either tie the
SEQ pin to V
When an analog voltage is applied to the SEQ pin,
the output voltage tracks this voltage until the output
reaches the set-point voltage. The SEQ voltage must
be set higher than the set-point voltage of the module.
The output voltage follows the voltage on the SEQ pin
on a one-to-one volt basis. By connecting multiple
modules together, customers can get multiple
modules to track their output voltages to the voltage
applied on the SEQ pin.
For proper voltage sequencing, first, input voltage is
applied to the module. The On/Off pin of the module
is left unconnected (or tied to GND for negative logic
modules or tied to V
that the module is ON by default. After applying input
voltage to the module, a minimum of 10msec delay is
required before applying voltage on the SEQ pin.
During this time, potential of 50mV (± 10 mV) is
maintained on the SEQ pin.
analog voltage is applied to the SEQ pin and the
output voltage of the module will track this voltage on
a one-to-one volt bases until output reaches the set-
point voltage. To initiate simultaneous shutdown of
the modules, the SEQ pin voltage is lowered in a
controlled manner. Output voltage of the modules
tracks the voltages below their set-point voltages on a
one-to-one basis. A valid input voltage must be
maintained until the tracking and output voltages
reach ground potential to ensure a controlled
shutdown of the modules.
When using the EZ-SEQUENCE
start-up of the module, pre-bias immunity feature
during start-up is disabled. The pre-bias immunity
feature of the module relies on the module being in
the diode-mode during start-up. When using the EZ-

internal set-up time of 10msec, and will be in
synchronous rectification mode when voltage at the
SEQ pin is applied. This will result in sinking current
in the module if pre-bias voltage is present at the
output of the module. When pre-bias immunity during
start-up is required, the EZ-SEQUENCE
must be disabled. For additional guidelines on using

Remote Sense
The Austin SuperLynx
have a Remote Sense feature to minimize the effects
of distribution losses by regulating the voltage at the
Remote Sense pin (See Figure 31). The voltage
between the Sense pin and Vo pin must not exceed
0.5V.
The amount of power delivered by the module is
defined as the output voltage multiplied by the output
current (Vo x Io). When using Remote Sense, the
output voltage of the module can increase, which if
the same output is maintained, increases the power
output by the module. Make sure that the maximum
output power of the module remains at or below the
maximum rated power. When the Remote Sense
feature is not being used, connect the Remote Sense
pin to output pin of the module
