ATR2815D

PD-94550B ATR28XXD SERIES HYBRID - HIGH RELIABILITY DC-DC CONVERTER Description 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. 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 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 environments. 28V Input, Dual Output ATR Features n n n n n n n n n 16V to 40VDC Input Range (28VDC Nominal) ±12V and ± 15V Outputs Available Indefinite Short Circuit and Overload Protection 3 35W/in Power Density 30W Output Power Fast Loop Response for Superior Transient Characteristics Operating Temperature Range from -55°C to +125°C Popular Industry Standard Pin-Out Resistance Seam Welded Case for Superior Lon...
