Product Summary
The ATW2805S/ES is an advanced analog hybrid-high reliability DC/DC converter. It features high power density and an extended temperature range for use in military and industrial applications. Designed to MIL-STD-704 input requirements, the ATW2805S/ES operates with a nominal 28 VDC inputs with ±12V and ±15V dual outputs to satisfy a wide range of requirements. The ATW2805S/ES 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.
