GENERAL DESCRIPTION
Our AM1S-N series is a family of cost effective 1W single
output isolated DC/DC converters. These converters
achieve low cost and ultra-miniature SIP4 pin size without
compromising performance and reliability.
Twenty models operate from input voltages of 5, 12 &
24VDC; producing output voltage levels of 5, 9, 12 &
15VDC. Full SMD-design and a 100 % production test of
parameters ensures a high reliability in this product.
