GENERAL DESCRIPTION
Our AM15EW-C series is a family of cost effective 15W single
output DC-DC converters. These converters are shielded on
all six sides and encapsulated with a nickel-coated copper
with a non-conductive base and dimensions of
50.8x25.4x10.5mm. The high performance features of
our AM15EW-C components include short circuit protec-
tion with current limit auto recovery, tight line regulation
and a high efficiency operation coefficient up to 83%.
These wide range devices operate over 4:1 input voltage
range, providing a continuously stable output voltage.
Ten models operate from an input voltage range of 24 &
48VDCproducing output voltages of 3,3, 5, 12, 15 &
24VDC. The normal operation is specified over the full
operating temperature range of -25°C to +71°C with no
derating required. Cooling is done by free air convection.
