GENERAL DESCRIPTION
Our AM4TW series is a family of cost effective 4W single and dual
output DC-DC converters. These converters combine a nickel-
coated copper package in a 24-pin DIP compatible case with high
performance features such as 1500 & 3500VDC input/output isola-
tion voltage, 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 80%
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.
