| Single and Dual Output Isolated DC/DC Converters | ||
| Open-frame, single board construction for higher reliability |
 |
Single and dual output dc-dc converter are composed of next-generation, board-mountable, isolated, fixed switching frequency dc-dc converters that use synchronous rectification to achieve extremely high power conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate. |
