Three standard temperature grades are offered with screening options. Refer to Part Number section. They can be provided in a standard plug-in package for PC mounting or in a flanged package for more severe en- vironments. These converters are manufactured in a facility certi- fied to MIL-PRF-38534. All processes used to manu- facture these converters have been qualified to enable Advanced Analog to deliver compliant devices. Four screening grades are available to satisfy a wide range of requirements. The CH grade converters are fully compliant to MIL-PRF-38534 for class H. The HB grade converters are processed to full class H screen- ing but do not have class H element evaluation as re- quired by MIL-PRF-38534. Both grades are fully tested and operate over the full military temperature range without derating of output power. The ES version is a full temperature device without the full class H or ele- ment evaluation. The non-suffix device is a low cost limited temperature range option. Variations in electrical, mechanical and screening can be ac- commodated. Extensive computer simulation using complex modeling enables rapid design modification to be provided. Contact Advanced Analog with spe- cific requirements. The ATR28XXD Series of DC/DC converters feature high power density and an extended temperature range for use in military and industrial applications. Designed to MIL-STD-704D input requirements, these devices have nominal 28VDC inputs with ±12V and ±15V dual outputs to satisfy a wide range of requirements. The circuit design incorporates a pulse width modulated single forward topology operating in the feed-forward mode at a nominal switching frequency of 550KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits. PD - 94550 |
