output voltage using an external resistor.
Voltage Margining
Output voltage margining can be implemented in the
12V PicoTLynx
resistor, R
for margining-up the output voltage and by
connecting a resistor, R
output pin for margining-down. Figure 46 shows the
circuit configuration for output voltage margining.
The POL Programming Tool, available at
www.lineagepower.com
section, also calculates the values of R
R
margin. Please consult your local Lineage Power
technical representative for additional details.

Monotonic Start-up and Shutdown

start-up and shutdown behavior for any combination
of rated input voltage, output current and operating
temperature range.
Startup into Pre-biased Output
The 12V Pico TLynx
prebiased output as long as the prebias voltage is
0.5V less than the set output voltage. Note that
prebias operation is not supported when output
voltage sequencing is used.
Output Voltage Sequencing
The 12V PicoTLynx
include a sequencing feature, EZ-SEQUENCE that
enables 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 volt 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
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.
During this time, a voltage of 50mV (± 20 mV) is
maintained 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. 47) according to the
following equation
the voltage at the sequencing pin will be 50mV when
the sequencing signal is at zero.
