UL/cUL 60950, EN 60950 Description Pin-Out Information
nation of input-output isolation and a
wide-input voltage range, allows operation
from either +24 V or –48 V. The wideoutput adjust enables the output voltage
to be set to to any voltage over the range,
1.8 V to 3.6 V, using a single external
resistor. Precise output voltage regulation is assured using Smart-Sense. This
is a differential remote sense that will
intelligently regulate the sequenced output, depending on its sequence status.
Other operational features include an
input under-voltage lockout (UVLO) and
an output enable control. Over-current,
over-voltage, and over-temperature protection assures the module’s ability to
survive any load fault.
Typical applications include distributed
power architectures in both telecom and …
