DC-DC Converters

AC-DC Power Supplies


100W, 9-53V Input Non-isolated DC-DC Converters

The i3A converters are ideal for creating additional mid-current output voltages from a single output 12V, 24V, 36V or 48V AC-DC power supply. These 100W step-down converters can accept a wide 9 to 53Vdc input and deliver wide adjustable output voltages of 3.3 to 16.5V at up to 8A or 5 to 30V at up to 4.5A. With efficiencies of up to 98%, the 1/32nd brick format non-isolated converters offer a very cost effective solution, with minimal derating at high ambient temperatures. The i3A series are suitable for use in medical, communications, industrial, test and measurement, broadcast and portable equipment.
