GENERAL DESCRIPTION
Our AM1/4L-N series is a family of cost effective
1/4W single and dual output DC/DC converters.
These converters combine a miniature SMD pack-
age and high performance features such as a 1000 &
3000VDC input/output isolation voltages, continu-
ous short circuit protection and a tight line / load
regulation.
96 models operate from input voltages of 3.3, 5, 12 and
24VDC producing output voltages of 3.3, 5, 9, 12, 15,
24, ±5, ±9, ±12, ±15 & ±24VDC. Full SMD design
and a 100% production test of parameters ensures a
high reliability in this product.
