Description
The L Single- and Dual-Output-Series Power Modules are low-profile, dc-dc converters that operate over an
input voltage range of 18 Vdc to 36 Vdc or 36 Vdc to 75 Vdc and provide one or two precisely regulated out-
puts. The outputs are isolated from the input, allowing versatile polarity configurations and grounding connec-
tions. The modules have a maximum power rating of 10 W to 15 W and efficiencies of up to 84% for a 5 V
output and 82% for a 3.3 V output. Built-in filtering for both input and output minimizes the need for external fil-
tering.

Turn-on Delay and Rise Times
(At 80% of IO, max; TA = 25 °C; see Figures 31
and 32.):
Case 1: On/Off Input Is Set for Unit On and
then Input Power Is Applied (delay from
point at which VI = VI, min until VO = 10% of
VO, nom).
Case 2: Input Power Is Applied for at Least
One Second, and then the On/Off Input Is
Set to Turn the Module On (delay from
point at which on/off input is toggled until
VO = 10% of VO, nom).
