ULS 60-Watt Series
Sixteenth-brick DOSA-Compatible,
Isolated DC/DC Converters
Dynamic control of the remote on/off function is best accomplished with a
mechanical relay or an open-collector/open-drain drive circuit (optically isolated
if appropriate). The drive circuit should be able to sink appropriate current (see
Performance Speci?cations) when activated and withstand appropriate voltage
when deactivated. Applying an external voltage to pin 2 when no input power is
applied to the converter can cause permanent damage to the converter.

Connect sense to its respective V OUT pin if sense is not used with a remote load.
Note: “Δ” is always a positive value.
“V NOM ” is the nominal, rated output voltage.
“V OUT ” is the desired, changed output voltage.
