AM3TW Series  
3 watt dc-dc converters  
24-PIN DIP PACKAGE  
INPUT/OUTPUT ISOLATION: 1500 & 3500VDC  
OPERATING TEMPERATURE: -40°C ... +85°C  
PIN-COMPATIBLE WITH MULTIPLE MANUFACTURERS  
CONTINUOUS SHORT CIRCUIT PROTECTION  
LOW PROFILE METAL PACKAGE  
HIGH EFFICIENCY UP TO 79%  
WIDE 4:1 INPUT RANGE  
GENERAL DESCRIPTION  
& 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.  
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
