LS-SERIES

(28V Input, Single/Dual Output)

Table 2: Dual Output Voltage Ranges and Constants

Note:

(1). Also the minimum and maximum adjustment limits of the output voltage.

Placement of Radj

An external resistor must be added in order to trim the output voltage of an LS converter. The placement

of an Radj resistor (Rdown or Rup) must be as shown in Figure 1 for single output models and as per

Figure 2 for dual output models. Please note that the connections are made to the specific pins. Rup is

placed across Out Return and Out Adj pins for output voltage greater than nominal output. Similar

connections apply for the dual output models.
