GENERAL DESCRIPTION
Our AM3T-N series is a family of cost effective 3W
single and dual output DC/DC converters. These
converters combine a shielded metal package in a
24-pin DIP compatible case and includes high per-
formance features such as a 1500VDC input/output
isolation voltage, continuous short circuit protection
and a tight line / load regulation. Wide range devices
operate over a 2:1 input voltage range continuously
providing a stable output voltage.
32 models operate from input voltages of 5, 12, 24 and
48VDC with output voltages of 3.3, 5, 12, 15, ±5, ±9,
±12, ±15VDC. High performance features include high
efficiency operation up to 83% and output voltage
accuracy of ±1%. All models are packaged in a low
profile 31.75 x 20.32 x 9.45mm case. Operation is
specified over the full operating temperature range of
-40°C to +85°C with no derating required. Cooling is
by free-air convection.
