GENERAL DESCRIPTION
Our AM3T series is a family of cost effective 3W single
and dual output DC-DC converters. These converters
combine nickel-coated copper package in a 24-pin DIP
compatible case with high performance features such as
1500 & 3500VDC input/output isolation voltage, continu-
ous short circuit protection with automatic restart and tight
line / load regulation. Wide range devices operate over 2:1
input voltage range providing stable output
voltage. Devices are encapsulated using flame retardant
resin. Ninety six models operate from input voltages of 12,
24 & 48VDC with output voltages of 3.3, 5, 7.2, 9, 12, 15,
18, 24, ±3.3, ±5, ±7.2, ±9, ±12, ±15, ±18 & ±24VDC.
High performance features include high efficiency opera-
tion up to 79% and output voltage accuracy of ±1%
maximum. All models are package in a low profile 31.75
x 20.32 x 10.16mm 24 pin DIP nickel-coated copper 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.
