Sequencing Function
Bourns XT Series modules have a sequencing feature that enables users to implement various types of output voltage sequencing in
their applications. 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 SEQ pin 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, customers can get multiple modules to track
their output voltages to the voltage applied on the SEQ pin.
For proper voltage sequencing, the input voltage is applied to the module. The On/Off pin should be set so as the module is ON by
default. An analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a 1:1 basis until
output reaches the set-point voltage, as shown in Figure 27.
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, as shown in Figure 28. 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 not using the sequencing feature, tie the SEQ pin to V out . For additional guidelines please contact your local Bourns field
applications engineer.
Voltage Margining
Output voltage margining can be implemented as follows and as shown in Figure 26.
Please consult your local Bourns field applications engineer for more details and the calculation of the required resistor values.

Operating Information (Continued)
1) Trim-up: Connect a resistor, Rm-up, from the Trim pin to the ground pin for adjusting the voltage upwards, and
2) Trim-down: Connect a resistor, Rm-down, from the Trim pin to the output pin for adjusting the voltage downwards.
