The IQ24-QTA family of isolated DC/DC converters offers up to 93% efficiency. Its members come in 18 to 36V input versions and can deliver 120W of output in an industry-standard 1/4-brick footprint and pin-out. Single-output configurations available are 1.8V/40A, 3.3V/30A, 5V/24A, 7V/17A, 12V/10A, 15V/8A, 24V/5A, 30V/4A and 48V/2.5A. However, thanks to the wide output-voltage trim range of +10/-20%, a variety of different voltages can actually be provided between 1.45 and 53V. Further, the basic-grade galvanic isolation between input and output of 2250VDC means the modules can either be configured to supply a positive or negative output, or can be wired in series to create higher output voltages. The devices are available in one of three mechanical configurations: open-frame for convection-cooled applications, with an attached baseplate for conduction-cooled applications, and fully encapsulated for harsh-environment applications. The encapsulated option brings the additional benefit of having reinforced-grade isolation from input to output. The series is capable of withstanding transients on the input up to 50V for 100ms. Calculated MTBF figures are in excess of 2MHrs, and all units are fully 6/6 RoHS-compliant. The operating temperature range is -40 to +100˚C.
