Description

The ATOVP1 is a high power density DC/DC converter designed for military and industrial applications. It is part of the ATO28XXT Series and features an extended temperature range. The converter is designed to meet the nominal input requirements of MIL-STD-704D, with 28VDC nominal inputs and +5V and ±12V or +5V and ±15V triple outputs. The circuit design incorporates a pulse width modulated push-pull topology operating at a nominal switching frequency of 250KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits.
