Output Voltage Sequencing
The 12V Mega TLynx
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 final value of 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 basis.
By connecting multiple modules together, multiple
modules can 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
modules) so that the module is ON by default. After
applying input voltage to the module, a minimum
10msec delay is required before applying voltage
on the SEQ pin. This delay gives the module
enough time to complete its internal power-up soft-
start cycle. During the delay time, the SEQ pin
should be held close to ground (nominally 50mV ±
20 mV). This is required to keep the internal op-amp
out of saturation thus preventing output overshoot
during the start of the sequencing ramp. By
selecting resistor R1 (see fig. 33) according to the
following equation

the voltage at the sequencing pin will be 50mV
when the sequencing signal is at zero.

sequencing signal to the SEQ pin.
After the 10msec delay, an 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 the output reaches the set-point voltage.
To initiate simultaneous shutdown of the modules,
the SEQ pin voltage is lowered in a controlled
manner. The 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.
When using the EZ-SEQUENCE
control start-up of the module, pre-bias immunity
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-SEQUENCE
an internal set-up time of 10msec, and will be in
synchronous rectification mode when the voltage at
the SEQ pin is applied. This will result in the
module sinking current if a pre-bias voltage is
present at the output of the module. When pre-bias
immunity during start-up is required, the EZ-
