GENERAL DESCRIPTION

Our AM5TW-C series is a family of cost effective 5W single and

dual output DC-DC converters. These shielded converters are

aluminum encapsulated on all six sides, have a non-conduc-

tive base & retain an anodized black DIP24 compatible

plastic case (31.8x20.3x10.2mm). The high performance

features of AM5TW-C series include current limit auto

recovery short circuit protection, tight line regulation and

high efficiency operation coefficient up to 78%.

These wide range devices operate over 4:1 input voltage

range, providing a continuously stable output voltage. Input

voltage range of 24 & 48VDC converts in output voltages

of 3.3, 5, 12, 15, 24, ±5, ±12 & ±15VDC. The normal oper-

ation 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.
