Ordering Information
Part Number Suffixes
Standard DLV DC/DC’s provide a Trim function (Pin 9) for the lower
of the two output voltages. A Trim pin (Pin 5) for the higher voltage can
be added by indicating a "T" suffix. A Sync pin can also be added and
is indicated by an "S" suffix. An "N" suffix indicates that the On/Off
Control function incorporates negative polarity logic. An "I" suffix provides
independent on/off control (Pin 4) for the higher output voltage.
No Suffix Pins 3 & 5 not installed, positive polarity On/Off Control
T Suffix Pin 5 added for higher voltage Trim option
S Suffix Pin 3 added for Sync Option
N Suffix Negative polarity On/Off Control
I Suffix Pin 4 independent on/off control of Pin 6 output voltage
