HYBRID-HIGH RELIABILITY DC/DC CONVERTERS PD-94557A ATW28XXD SERIES 28V Input, Dual Output Description The ATW28XXD 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-704 input requirements, these devices operate with a nominal 28VDC inputs with ±12V and ±15V dual 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 270KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits.
