GENERAL DESCRIPTION
Our AM8TW-I series is a family of cost effective
8W single and dual output DC-DC converters.
These converters are DIP24 compatible metal case
with dimensions of 31.8x20.3x10.2mm. The high
performance features of our AM8TW-I components
include continuous short circuit protection with
auto recovery, tight line regulation and a high effi-
ciency operation coefficient up to 84%.
These wide range devices operate over 4:1 input
voltage range, providing a continuously stable out-
put voltage. Fourteen models operate from an input
voltage range of 24 & 48VDC producing output
voltages of 3.3, 5, 12, 15, ±5, ±12 & ±15VDC. The
normal operation is specified over the full operating
temperature range of -40°C to +75°C with no derat-
ing required. Cooling is done by free air convec-
tion.
