ASA2805D

PD-94540A ASA28XXD SERIES 28V Input, Dual Output HYBRID-HIGH RELIABILITY DC/DC CONVERTER Description The ASA28XXD Series of DC/DC converters are high reliability thick film hybrid converters that use flyback topology operating at a nominal frequency of 550KHz. High input to output isolation is achieved through the use of transformers in the flyback power and feed back circuits. The advanced feedback design provides fast loop response for superior line and load transient characteristics and offers greater reliability than devices incorporating optical feedback circuits. This device is designed to meet MIL-STD-704 input requirements offering full performance over a 16V to 40V input range. Output Power of up to 5W is available for either balanced or unbalanced loads. Connecting the inhibit pin (pin 5) to the input common (pin 7) will cause the converter to shut down. It is recommended that the inhibit pin be driven by an open collector device capable of sinking at least 400µA. The open circuit voltage of the inhibit pin is 11.5 ± 0.5V. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are fabricated utilizing DSCC qualified processes. For available screening options, refer to device screening table in the data sheet. Variations in electrical, mechanical and screening can be accommodated. Extensive computer simulation using complex modeling enables rapid design modification to be provided. Contact IR Santa Clara with specific requirements. www.DataShe...
