AT SERIES (2” x 1” Package)
Up to 30 Watt DC-DC Converter
PRODUCT OVERVIEW
The AT series offer up to 30 watts of output power in standard 2.00 x 1.00 x 0.4 inches
packages. This series features high efficiency and 1500 Volts of DC isolation. The AT
series provides a 4:1 wide input voltage range of 9 to 36 or 18 to 75VDC, and delivers
accurate regulated output. These modules operate over the ambient operating
temperature range of –40°C to +85°C. These converters are fully protected against input
UVLO (Under Voltage Lock Out), over-current, over-voltage and continuous short circuit
protection. In addition, the option control functions include Positive Remote On/Off and
adjustable output voltage.
