ATO2815T

PD - 94582A ATO28XXT SERIES 28V Input, Triple Output HYBRID-HIGH RELIABILITY DC/DC CONVERTER Description The ATO28XXT Series of DC/DC converters feature high power density and an extended temperature range for use in military and industrial applications. Designed to the nominal input requirements of MIL-STD-704D, these devices have nominal 28VDC inputs with +5V and ±12V or +5V and ±15V triple outputs to satisfy a wide range of requirements. The circuit design incorporates a pulse width modulated push-pull topology operating in the feed-forward mode at a nominal switching frequency of 250KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits. The advanced feedback design provides fast loop response for superior line and load transient characteristics and offers greater reliability and radiation tolerance than devices incorporating optical feedback circuits. Three standard temperature grades are offered. Refer to Part Numbering section. They are provided in a standard plug-in package for PC mounting or in a flanged package for more severe environments. 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 modest design modifications t...
