EN/LZT 146 30 R2A Ericsson Microelectronics AB, October 2000
NOTES:
1)
The input voltage range 38…72 V dc meets
the European Telecom Standard prETS
300 132-2 Nominal input voltage range in
48 V and 60 V dc power systems,
– 40.5… –57.0 V and –50.0… – 72.0 V
respectively. At input voltages exceeding 72 V
(abnormal voltage) the power loss will be
higher than at normal input voltage and TC
must be limited to max +95 °C. Absolute max
continuous input voltage is 75 V dc. Output
characteristics will be marginally affected at
input voltages exceeding 72 V.
2)
The power modules will operate down to
36 V, when VI decreases, but will turn on at
VI 38 V, when VI increases (see also Operating
information).
3)
The test is applicable for through-hole versions.
Stress in excess of Absolute Maximum
Ratings may cause permanent damage.
Absolute Maximum Ratings, sometimes
referred to as no destruction limits, are
normally tested with one parameter at a
time exceeding the limits of Output data
or Electrical Characteristics. If exposed to
stress above these limits, function and per-
formance may degrade in an unspecified
manner.
