GENERAL DESCRIPTION
Our AM3TW 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 perform-
ance features such as 1500 & 3500VDC input/output isolation volt-
age, continuous short circuit protection with automatic restart and
tight line / load regulation. Wide range devices operate over 4:1
input voltage range providing stable output voltage. Devices are
encapsulated using flame retardant resin. Input voltages of 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 operation up to 79% and output
voltage accuracy of ±1% maximum. All models are packaged in a
low profile 31.75x20.32x10.16mm 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.
