ASA2812S

PD-94539A ASA28XXS SERIES 28V Input, Single Output HYBRID-HIGH RELIABILITY DC/DC CONVERTER Description The ASA28XXS 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 feedback 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-704D input requirements offering full performance over a 16V to 40V input range. Output Power of up to 5W is available. 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 requirements can be accommodated. Extensive computer simulation using complex modeling allows design modifications to be examined. Contact IR Santa Clara with specific requirements. ASA Features Up To 5.0W Output Power 5V,...
